If you'd like to support our work, then consider making a donation, any support
is always welcome even if it's as low as $1!
You can also sponsor the development of a specific feature. Please contact
us in order to discuss the detail of the implementation.
HOW CAN I UPGRADE FROM A PREVIOUS VERSION ?
===========================================
!!! Be careful when you upgrade your multiOTP open source Virtual Appliance !!!
The multiOTP open source Virtual Appliance is using the files in
raspberry/boot-part/multiotp-tree/usr/local/bin/multiotp, with
config and backend folders defined to be located in /etc/multiotp/
If you are currently using the multiOTP open source Virtual Appliance, you can upgrade
the multiOTP version by copying the extracted content of the folder and subfolders from
raspberry/boot-part/multiotp-tree/usr/local/bin/multiotp to /usr/local/bin/multiotp
An update through the web interface should be available in the future
If you are currently using the multiOTP open source linux files, you can
upgrade your installation by copying the extracted content of the folder and
subfolders from linux to your current multiOTP folder
!!! since 5.0.4.6 under Linux, the config, devices, groups, tokens and users folders are now
always located in /etc/multiotp/. Please be sure to make the move when you are upgrading !!!
(before 5.0.4.6, theses subfolders where located just below the main multiOTP folder)
If you are currently using the multiOTP open source windows files, you can
upgrade your installation by copying the extracted content of the folder and
subfolders from windows to your current multiOTP folder
WHAT'S NEW IN THIS 5.9.x RELEASE
- LDAP filter can be customized
- Users without 2FA tokens don't see the second screen in the Credential Provider during logon
- New Raspberry, Hyper-V and OVA appliances available (version 011, based on Debian 11)
- Scratchlist can be generated from the Web GUI
- {MultiOtpDisplayName} (AD/LDAP DisplayName) can be used in templates

TYPICAL TREE OF A WORKING LINUX INSTALLATION
============================================
A typical installation has the following tree organization:
**Software files**
```
/usr/local/bin/
/usr/local/bin/multiotp (contains multiotp.php)
/usr/local/bin/multiotp/templates
```
**Data files**
```
/etc/multiotp/
/etc/multiotp/config (contains multiotp.ini)
/etc/multiotp/devices
/etc/multiotp/groups
/etc/multiotp/tokens
/etc/multiotp/users (contains my_user1.db, my_user2.db, ...)
```
HOW CAN I CREATE MYSELF THE DIFFERENT VERSIONS ?
================================================
The multiotp.php file is a copy of the multiotp.cli.header.php including
the copy of all files that are included in the PHP code, which are
multiotp.class.php and the whole contrib subfolder content.
For the virtual appliance and the Raspberry Pi edition, the multiotp.php file
is a copy of the multiotp.cli.proxy.php file.
(the proxy version calls the multiotp.proxy.php using the web server,
and the web server has a PHP cache to improve the speed of the whole process).
For the virtual appliance and the Raspberry Pi edition, the multiotp.proxy.php file is
a copy of the multiotp.cli.header.php including the copy of all files that are included
in the PHP code, which are multiotp.class.php and the whole contrib subfolder content.
For the virtual appliance and the Raspberry Pi edition, the following line in multiotp.class.php
```
$multiotp = new Multiotp('DefaultCliEncryptionKey', $initialize_backend, $folder_path);
```
is replaced by
```
$multiotp = new Multiotp('DefaultCliEncryptionKey', $initialize_backend, $folder_path);
if (false !== strpos(getcwd(), '/')) {
$multiotp->SetConfigFolder('/etc/multiotp/config/');
$multiotp->SetCacheFolder('/tmp/cache/');
$multiotp->SetDevicesFolder('/etc/multiotp/devices/');
$multiotp->SetGroupsFolder('/etc/multiotp/groups/');
$multiotp->SetTokensFolder('/etc/multiotp/tokens/');
$multiotp->SetUsersFolder('/etc/multiotp/users/');
$multiotp->SetLogFolder('/var/log/multiotp/');
$multiotp->ReadConfigData();
}
$multiotp->SetLinuxFileMode('0666');
```
The multiotp.exe is a stub launcher running a PHP interpreter.
The necessary files of the PHP distribution are included in the php subfolder.
PHP download : http://php.net/downloads.php
The source files of the Credential provider are available on GitHub and needs
the free Visual Studio Community to be compiled.
Source files : https://github.com/multiOTP/multiOTPCredentialProvider
Visual Studio Community : https://www.visualstudio.com/vs/community/
WHEN AND HOW CAN I USE THIS PACKAGE ?
=====================================
If you decide to have strong two factor authentication inside your company,
this is definitely the package you need! You will be able to have strong
authentication for your VPN accesses, your SSL gateway, your private websites
and even your Windows login for desktops AND laptops!
The multiOTP class can be used alone (for example to have strong
authentication for your PHP based web application), as a command line tool
(to handle users and have strong authentication using command line), as a web
service (to provide centralized authentication for a client/server installation)
or finally coupled with a radius server like TekRADIUS or FreeRADIUS to be able
to have a strong two factor authentication through the RADIUS protocol for
external devices like for example firewalls or captive portals.
The default backend storage is done in flat files, but you can also defined a
MySQL server as the backend server. To use MySQL, you will only have to provide
the server, the username, the password and the database name. Tables will be
created/updated automatically by multiOTP. The schema is also upgraded
automatically if you install a new release of multiOTP.
Starting with version 4.x, you can also install a multiOTP web service
on a server, and this way some other multiOTP slave clients (like laptops)
can connect to the web service and caching the tokens information (if allowed).
Inside a company, you will probably use multiOTP with a radius server or as
a web service (see below on how to install these services).
If you are running under Windows, TekRADIUS or TekRADIUS LT will do the job
(http:/www.tekradius.com/).
The difference is that TekRADIUS needs an MS-SQL SERVER (or MS-SQL Express)
and TekRADIUS LT uses only an embedded SQLite database.
multiOTP is working fine under Windows with WinRADIUS, a port of FreeRADIUS
(http://winradius.eu/)
multiOTP is also working fine with another port of FreeRADIUS
for Windows (http://sourceforge.net/projects/freeradius/)
If you are running under Linux, FreeRADIUS will do the job.
(http://freeradius.org/)
Now, you can register your different devices like firewalls, SSL, etc.
in the radius server and provide the IP address(es) of the device(s)
(often called NAS) and their shared Secret.
If you want to have strong authentication on Windows logon, have a look at the
open source project multiOTPCredentialProvider which is based on MultiotpCPV2RDP
from arcadejust and MultiOneTimePassword Credential Provider from Last Squirrel IT.
It works with Windows 7/8/8.1/10/11/2012(R2)/2016/2019/2022 in 64 bits.
The Credential Provider does not need any RADIUS connection! It uses instead a
local version of multiOTP which can be configured as a client of a
centralized server (with caching support).
(https://download.multiotp.net/credential-provider/)
When the backend is set, it's time to create/define the tokens. You will have
to select hardware or software token generators for your users. Currently, the
library supports mOTP, TOTP, HOTP, SMS or scratch passwords (printed on paper).
mOTP is a free implementation of strong tokens that asks a PIN to generate a
code. This code depends of the time and the PIN typed by the user.
A special without2FA token type is also available. It could be useful to do 2FA
only for some accounts and not for others.
The easiest tokens to use are TOTP, they are time based and well supported by
a lot of implementations like Google Authenticator.
Provisioning will be done simply by flashing a QRcode.

(seed is extracted from the importAlpine.dat downloaded file,
the seed is the sccKey attribute)
- ZyWALL OTPv1 (rebranded Authenex A-Key 3600): OATH/HOTP, 6 digits
(seed is extracted from the OTP_data01_upgrade.sql SQL file,
SEED field at the end of the file)

- YubiKey standard
- YubiKey Nano
- YubiKey Neo
- YubiKey Neo-N
If you want to use software tokens with Apps like Google Authenticator, you can
create a QRcode provisioning in two EASY steps with the command line tool:
- create the token for the user (without prefix PIN request):
multiotp -fastcreatenopin my_user
- generate the provisioning QRcode: multiotp -qrcode my_user my_qrcode.png
You can also create a user quickly with the prefix PIN request option based on
the default option set in your configuration: multiotp -fastcreate my_user
And of course, you can also force to create a user quickly with a requested
prefix PIN: multiotp -fastcreatewithpin my_user
WHAT IS THE PREFIX PIN OPTION ?
===============================
The prefix PIN option is activated by default. Users will have to type their
PIN + the displayed token. The prefix PIN option has no effect for mOTP tokens,
and the users MUST NOT type their prefix PIN before the displayed token for
mOTP tokens, as the prefix PIN is already used by the algorithm in order to
generate the token.
Starting with version 4.3, it's now possible to use the synchronized AD/LDAP
password as a prefix instead of the static PIN. Please note that even with the
AD/LDAP password as a prefix activated, the PIN used for mOTP tokens is still
the static PIN.
To create a user quickly with the prefix PIN request option based on
the default option set in your configuration: multiotp -fastcreate my_user
To create a user quickly without a prefix PIN request:
multiotp -fastcreatenopin my_user
To create a user quickly with a requested prefix PIN:
multiotp -fastcreatewithpin my_user
HOW THE LOCKOUT OF AN ACCOUNT IS WORKING ?
==========================================
To prevent brute-force attack, an account is temporary locked for 300 seconds
after 3 unsuccessful trials.
After 6 unsuccessful trials, the account is definitely locked.
A user is unlocked by typing the following command line:
multiotp -unlock user
A user can also unlock his account by typing two consecutive codes,
separated by a space (don't forget the prefix PIN/password if enabled).
If prefix PIN is enabled, your PIN is 1234 and the two consecutive tokens are
984501 and 348202, you will have to type "1234984501 1234348202" as the
password in order to unlock the account during authentication.
The lockout parameters can be modified using these command lines:
multiotp -config failure-delayed-time=60
multiotp -config max-block-failures=12
multiotp -config max-delayed-failures=10
HOW TO DEBUG ?
==============
In order to have debug information, you can use the -debug option. With this
option, the debug information are saved in the file log/multiotp.log.
If you want to see directly the debug information on screen, add the
-display-log and an output of the debug information will be done on screen too.
In order to enable the debug mode permanently without using the option, you can
do that like this: multiotp -config debug=1
The same thing can be done for a permanent display of the debug information on
the screen without using the option: multiotp -config display-log=1
HOW TO INSTALL THE MULTIOTP WEB SERVICE UNDER WINDOWS ?
=======================================================
Installing the multiOTP web service is VERY easy. Simply run the
webservice_install script. Nginx configuration file will be created,
firewall rules will be adapted and the service will be installed and started.
The service is called multiOTPservice and is listening on port 8112 (http)
and on port 8113 (https).
HOW TO INSTALL THE MULTIOTP RADIUS SERVER UNDER WINDOWS ?
=========================================================
Installing the multiOTP radius service is VERY easy too. Simply run the
radius_install script. The etc/raddb/modules/multiotp file will be created,
firewall rules will be adapted and the service will be installed and started.
The service is called multiOTPradius and the secret is multiotpsecret for any
client including 127.0.0.1.
CONFIGURING MULTIOTP WITH TEKRADIUS OR TEKRADIUS LT UNDER WINDOWS
=================================================================
TekRADIUS supports a Default Username to be used when a matching user
profile cannot be found for an incoming RADIUS authentication request.
So a quick and easy way is to create in the TekRADIUS Manager a User
named 'Default' that belongs to the existing 'Default' Group.
Then add to this Default user the following attribute :
Check External-Executable C:\multitop\multiotp.exe %ietf|1% %ietf|2% -chap-challenge=%ietf|60% -chap-password=%ietf|3% -ms-chap-challenge=%msoft|11% -ms-chap-response=%msoft|1% -ms-chap2-response=%msoft|25%
Some values can go back to TekRADIUS:
a) Set the right format options for TekRADIUS:
multiotp -config radius-reply-attributor="=" radius-reply-separator="crlf"
b) Set multiOTP to send back to TekRADIUS the clear (non encrypted) authentication:
multiotp -config clear-otp-attribute="ietf|2"
c) Set multiOTP to send back to TekRADIUS the group of the authenticated user:
multiotp -config group-attribute="ietf|11"
HOW TO INSTALL THE MULTIOTP WEB SERVICE UNDER LINUX ?
=====================================================
The multiOTP web service is a simple web site. If you are under Linux and you
are reading this document, you have for sure the necessary skill to configure
your favorite web server in order to have an URL that will launch the page
multiotp.server.php which is in the main folder of the multiOTP distribution.
Please check carefully the rights of the folders, as the multiOTP web service
has to write in the various subfolders.
CONFIGURING MULTIOTP WITH FREERADIUS 2.X UNDER LINUX
====================================================
Using the -request-nt-key option, NT_KEY: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX can
now be displayed (like with the same option used with ntlm_auth).
1) Create a new module file called "multiotp" in etc/raddb/modules/ containing:
```
# Exec module instance for multiOTP (https://www.multiotp.net/).
# for Linux : replace '/path/to/multiotp' with the actual path to the multiotp.php file, including the full file name.
# for Windows: replace '/path/to' with the actual path to the multiotp.exe file (also with /), including the fulle file name.
exec multiotp {
wait = yes

shell_escape = yes
}
```
2) In the configuration file called "default" in etc/raddb/sites-enabled/
```
a) Add the multiOTP handling
#
# Handle multiOTP (https://www.multiotp.net/) authentication.
# This must be added BEFORE the first "pap" entry found in the file.
multiotp
```
```
b) Add the multiOTP authentication handling
#
# Handle multiOTP (https://www.multiotp.net/) authentication.
# This must be added BEFORE the first "Auth-Type PAP" entry found in the file.
Auth-Type multiotp {
multiotp
}
```
```
c) Comment the first line containing only "chap"
#chap is now handled by multiOTP
```
```
d) Comment the first line containing only "mschap"
#mschap is now handled by multiOTP
```
3) In the configuration file called "inner-tunnel" in etc/raddb/sites-enabled/
```
a) Add the multiOTP handling
#
# Handle multiOTP (https://www.multiotp.net/) authentication.
# This must be added BEFORE the first "pap" entry found in the file.
multiotp
```
```
b) Add the multiOTP authentication handling
#
# Handle multiOTP (https://www.multiotp.net/) authentication.
# This must be added BEFORE the first "Auth-Type PAP" entry found in the file.
Auth-Type multiotp {
multiotp

```
```
c) Comment the first line containing only "chap"
#chap is now handled by multiOTP
```
```
d) Comment the first line containing only "mschap"
#mschap is now handled by multiOTP
```
4) In the configuration file called "policy.conf" in etc/raddb/
Add the multiOTP authorization policy
```
#
# Handle multiOTP (https://www.multiotp.net/) authorization policy.
# This must be added just before the last "}"
multiotp.authorize {
if (!control:Auth-Type) {
update control {
Auth-Type := multiotp
}
}
}
```
5) In the configuration file called "radiusd.conf" in etc/raddb/
Depending which port(s) and/or ip address(es) you want to listen, change
the corresponding ipaddr and port parameters
6) In the configuration file called "clients.conf" in etc/raddb/
Add the clients IP, mask and secret that you want to authorize.
```
#
# Handle multiOTP (https://www.multiotp.net/) for some clients.
client 0.0.0.0 {
netmask = 0
secret = multiotpsecret
}
```
7) Now, to see what's going on, you can:
- stop the service : /etc/init.d/freeradius stop
- launch the FreeRADIUS server in debug mode : /usr/sbin/freeradius -X
- try to make some authentication requests
8) When you have checked that everything works well:
- stop the debug mode (CTRL + C)
- restart the service /etc/init.d/freeradius restart
Some values can go back to FreeRADIUS:
* Set the right format options for FreeRADIUS:
multiotp -config radius-reply-attributor=" += " radius-reply-separator=","
* Set multiOTP to send back to FreeRADIUS the group of the authenticated user:
multiotp -config group-attribute="Filter-Id"
CONFIGURING MULTIOTP WITH FREERADIUS 3.X UNDER LINUX
====================================================
Source: https://wiki.freeradius.org/guide/multiOTP-HOWTO
multiOTP tokens will work with any type of PAP/CHAP/MS-CHAP/MS-CHAPv2 based authentication, including EAP-TTLS-PAP. With the correct OS/Supplicant software tokens can be used for 802.1X authentication and well as for standard PAP/CHAP/MS-CHAP/MS-CHAPv2 authentication (just make the changes described in the inner server). This guide closely follows the NTLM Auth with PAP HOWTO but with a little extra validation.
NT_KEY generation is also supported using the -request-nt-key option (like for ntlm_auth --request-nt-key option), which is needed in order to enable VPN (PPTP + MPPE) with MS-CHAP/MS-CHAPv2.
Before starting or asking for help
- Make sure the otp script is executable chmod +x /path/to/multiotp.php
- Verify multiotp is setup correctly by calling the script from the commandline with the appropriate arguments
1) Create '/etc/freeradius/3.0/mods-available/multiotp' and add the following, this will create a new instance of the exec module:
```
# Exec module instance for multiOTP
# Replace '/path/to' with the actual path to the multiotp.php file
exec multiotp {
wait = yes
input_pairs = request
output_pairs = reply
program = "/path/to/multiotp.php -base-dir='/path/to/multiotp/' '%{User-Name}' '%{User-Password}' -src='%{Packet-Src-IP-Address}' -tag='%{Client-Shortname}' -mac='%{Called-Station-Id}' -calling-ip='%{Framed-IP-Address}' -calling-mac='%{Calling-Station-Id}' -chap-challenge='%{CHAP-Challenge}' -chap-password='%{CHAP-Password}' -ms-chap-challenge='%{MS-CHAP-Challenge}' -ms-chap-response='%{MS-CHAP-Response}' -ms-chap2-response='%{MS-CHAP2-Response}' -state='%{State}'"
shell_escape = yes
}
```
2) Enable multiotp module by creating a symbolic link
```
ln -s /etc/freeradius/3.0/mods-available/multiotp /etc/freeradius/3.0/mods-enabled/multiotp
```
3) Copy /etc/freeradius/3.0/mods-available/mschap to /etc/freeradius/3.0/mods-available/multiotpmschap. Change the following line in multiotpmschap:
```
"mschap {"
```
to
```
"mschap multiotpmschap {"
```
Also change ntlm_auth variable:
```
ntlm_auth = "/path/to/multiotp.php -base-dir='/path/to/multiotp/' '%{User-Name}' '%{User-Password}' -nt-key-only -src='%{Packet-Src-IP-Address}' -tag='%{Client-Shortname}' -mac='%{Called-Station-Id}' -calling-ip='%{Framed-IP-Address}' -calling-mac='%{Calling-Station-Id}' -chap-challenge='%{CHAP-Challenge}' -chap-password='%{CHAP-Password}' -ms-chap-challenge='%{MS-CHAP-Challenge}' -ms-chap-response='%{MS-CHAP-Response}' -ms-chap2-response='%{MS-CHAP2-Response}' -state='%{State}'"
```
4) Enable multiotpmschap module by creating a symbolic link
```
ln -s /etc/freeradius/3.0/mods-available/multiotpmschap /etc/freeradius/3.0/mods-enabled/multiotpmschap
```
5) Edit /etc/freeradius/3.0/mods-available/perl file. Change the following line :
```
filename =
```
to
```
filename = /path/to/multiotp/scripts/multiotp.pl
```
Since 5.8.3.0 and FreeRADIUS 3.0.18, set the perl flags to -U
```
perl_flags = "-U"
```
6) Enable perl module by creating a symbolic link
```
ln -s /etc/freeradius/3.0/mods-available/perl /etc/freeradius/3.0/mods-enabled/perl
```
7)If necessary change multiOTP path in the multiOTP perl file scripts/multiotp.pl
```
my $output=`/usr/local/bin/multiotp/multiotp.php -base-dir='/usr/local/bin/multiotp/' "$multiotp_
```
to
```
my $output=`/path/to/multiotp.php -base-dir='/path/to/multiotp/' "$multiotp_
```
7) Create /etc/freeradius/3.0/policy.d/multiotp file and add the following to override the authorize method of the exec module:
```
# Change to a specific prefix if you want to deal with normal PAP authentication as well as OTP
# e.g. "multiotp_prefix = 'otp:'"
multiotp_prefix = ''
multiotp.authorize {
# This test force multiOTP for any MS-CHAP(v2),CHAP and PAP attempt
if (control:Auth-Type == mschap) {
update control {
Auth-Type := multiotpmschap
}
}
elsif (control:Auth-Type == chap) {
update control {
Auth-Type := multiotp
}
}
elsif (!control:Auth-Type) {
update control {
Auth-Type := multiotp
}
}
}
```
8) Enable files and add perl just after files, in the authorize section of /etc/freeradius/3.0/sites-available/default. Add the following lines:
...
files
```
perl #multiotp
if (ok || updated) { #multiotp
update control { #multiotp
Auth-Type := Perl #multiotp
Client-Shortname = "%{Client-Shortname}" #multiotp
Packet-Src-IP-Address = "%{Packet-Src-IP-Address}" #multiotp
} #multiotp
} #multiotp
```
After logintime add the following line :
...
expiration
logintime
```
# Handle multiotp authentication
multiotp
```
9) Add a call to multiotp before the pap module in authenticate section of /etc/freeradius/3.0/sites-available/default. Add the following lines:
...
authenticate {
```
Auth-Type multiotp {
multiotp
} #multiotp
Auth-Type multiotpmschap {
multiotpmschap
} #multiotpmschap
Auth-Type Perl { #multiotp
perl #multiotp
} #multiotp
```
10) Add a call to perl in accounting section of /etc/freeradius/3.0/sites-available/default. Add the following lines:
...
accounting {
```
perl #multiotp
```
11) Enable multiotp, in the authorize section of /etc/freeradius/3.0/sites-available/inner-tunnel. Add the following lines:
After logintime add the following line :
...
expiration
logintime
```
# Handle multiotp authentication
multiotp
```
...
authenticate {
```
Auth-Type multiotp {
multiotp
} #multiotp
Auth-Type multiotpmschap {
multiotpmschap
} #multiotpmschap
Auth-Type Perl { #multiotp
perl #multiotp
} #multiotp
```
12) Start the server up in debug mode radiusd -X and test authentication
HOW TO CONFIGURE MULTIOTP TO SYNCHRONIZED THE USERS FROM AN ACTIVE DIRECTORY ?
==============================================================================
1) Decide if you want that by default, created users need to type a prefix PIN (1|0):
multiotp -config default-request-prefix-pin=1
2) Decide if you want that by default, created users need to type their
Active Directory password instead of PIN (1|0):
multiotp -config default-request-ldap-pwd=1
3) Set the AD/LDAP server type (1=Active Directory | 2=standard LDAP):
multiotp -config ldap-server-type=1
4) Set the user CN identifier (sAMAccountName, eventually userPrincipalName):
multiotp -config ldap-cn-identifier="sAMAccountName"
5) Set the group CN identifier (sAMAccountName for Active Directory):
multiotp -config ldap-group-cn-identifier="sAMAccountName"

9) Set the Active Directory server(s), comma separated:
multiotp -config ldap-domain-controllers=my.srv.com,ldaps://12.13.14.15:636
(you can define more than one server, and you can also use a SSL connection
only for one server, on a specific port)
10) Set the Base DN:
multiotp -config ldap-base-dn="DC=demo,DC=multiotp,DC=net"
(on a Microsoft Windows Server, the different values of the base DN of the
domain can be displayed using the command ECHO %USERDNSDOMAIN%, and the
result will be something like DEMO.MULTIOTP.NET)
11) Set the Bind DN (which is the account used to connect to the AD/LDAP):
multiotp -config ldap-bind-dn="CN=sync,CN=Users,DC=demo,DC=multiotp,DC=net"
(on a Microsoft Windows Server, the bind DN of the user can be displayed
using the command dsquery user -name sync, and the result will be
something like "CN=sync,CN=Users,DC=demo,DC=multiotp,DC=net")
12) Set the password of the user used to search in the Active Directory:
multiotp -config ldap-server-password="password_of_my_ldap_user"
13) In which groups users must be in the Active Directory in order to be added:
multiotp -config ldap-in-group="VPNuser,dialin"
14) Set the network timeout
multiotp -config ldap-network-timeout=10
15) Set the transaction time limit
multiotp -config ldap-time-limit=30
16) Activate the AD/LDAP support (0|1):
multiotp -config ldap-activated=1
17) Let's go for an AD/LDAP users synchronisation !
(users removed or deactivated in the AD/LDAP are deactivated in multiOTP)
multiotp -debug -display-log -ldap-users-sync
DON'T FORGET TO SCHEDULE A SCRIPT THAT WILL DO THE USERS SYNCHRONIZATION REGULARY!
HOW TO CONFIGURE MULTIOTP TO SYNCHRONIZED THE USERS FROM A STANDARD LDAP ?
==========================================================================
1) Decide if you want that by default, created users need to type a prefix PIN (1|0):
multiotp -config default-request-prefix-pin=1
2) Decide if you want that by default, created users need to type their
LDAP password instead of PIN (1|0):
multiotp -config default-request-ldap-pwd=1
3) Set the AD/LDAP server type (1=Active Directory | 2=standard LDAP):
multiotp -config ldap-server-type=2
4) Set the user CN identifier (uid for standard LDAP):
multiotp -config ldap-cn-identifier="uid"
5) Set the group CN identifier (cn for standard LDAP):
multiotp -config ldap-group-cn-identifier="cn"
6) Set the group attribute:
multiotp -config ldap-group-attribute="memberOf"
7) Decide if you want to use by default an SSL connection or not (0|1):
multiotp -config ldap-ssl=0
8) Set the default port (389=regular | 636=SSL connection):

(you can define more than one server, and you can also use a SSL connection
only for one server, on a specific port)
10) Set the Base DN:
multiotp -config ldap-base-dn="dc=demo,dc=multiotp,dc=net"
11) Set the Bind DN (which is the account used to connect to the AD/LDAP):
multiotp -config ldap-bind-dn="uid=sync,cn=users,dc=demo,dc=multiotp,dc=net"
12) Set the password of the user used to search in the LDAP directory:
multiotp -config ldap-server-password="password_of_my_ldap_user"
13) In which groups users must be in LDAP directory in order to be added:
multiotp -config ldap-in-group="VPNuser,dialin"
14) Set the network timeout
multiotp -config ldap-network-timeout=10
15) Set the transaction time limit
multiotp -config ldap-time-limit=30
16) (EXPERT ONLY) If needed, you can change the LDAP filter.
By default, the LDAP filter for standard LDAP is :
"(&(|(objectClass=posixAccount)(objectClass=user))({cn_identifier}={username}))"
You can use the following placeholders: {cn_identifier}, {username}, and {groups_filtering}
multiotp -config ldap-filter="(&(|(objectClass=posixAccount)(objectClass=user))({cn_identifier}={username}))"
17) Activate the AD/LDAP support (0|1):

(users removed or deactivated in the AD/LDAP are deactivated in multiOTP)
multiotp -debug -display-log -ldap-users-sync
DON'T FORGET TO SCHEDULE A SCRIPT THAT WILL DO THE USERS SYNCHRONIZATION REGULARY!
HOW TO CONFIGURE MULTIOTP TO USE THE CLIENT/SERVER FEATURE ?
============================================================
A) On the server
1) Install the multiOTP web service on the authentication server side. If you
are using the unmodified included installer to install it under Windows,
the URL for the multiOTP web service is http://ip.address.of.server:8112
The web service script installer is called webservice_install.cmd.
2) Set the shared secret key you will use to encode the data between the
server and the client: multiotp -config server-secret=MySharedSecret
(this command line will change the configuration file config/multiotp.ini)
3) If you want to allow the client to cache the data on its side, set the
options accordingly (enable the cache and define the lifetime of the cache):
multiotp -config server-cache-level=1 server-cache-lifetime=15552000
(this command line will change the configuration file config/multiotp.ini)
4) Create your users on the server using the CLI or the web GUI interface. If
you are using the unmodified included installer to install it under Windows,
the URL for the multiOTP web service is http://ip.address.of.server:8112
B) On the client(s)
1) Set the shared secret key you will use to encode the data between the
client and the server: multiotp -config server-secret=MySharedSecret
(this command line will change the configuration file config/multiotp.ini)
2) If you want to have cache support (if allowed by the multiOTP web service),
set the option accordingly: multiotp -config server-cache-level=1
(this command line will change the configuration file config/multiotp.ini)
3) Define the timeout after which you will switch to the next server(s), and
on the local cache if no server available: multiotp -config server-timeout=3
(this command line will change the configuration file config/multiotp.ini)
4) Last but not least, define the server(s) you want to connect with:
multiotp -config server-url=http://ip.address.of.server:8112;http://url2
(this command line will change the configuration file config/multiotp.ini)
If you want to connect with a commercial multiOTP appliance, the URL is
https://ip.address.of.commercial.multiotp.server
5) Check your installation on the client by typing
multiotp -display-log -log -debug "user" "token", where "user" is an
existing user and "token" is the generated token for this user.
If you have created a user with a prefix PIN, don't forget to type the prefix
PIN before the displayed token.
Example without a prefix PIN: multiotp test 457863
Example with the "1234" prefix PIN: multiotp test 1234457863
HOW TO INSTALL A LOCAL ONLY STRONG AUTHENTICATION ON A WINDOWS MACHINE ?
========================================================================
1) Install multiOTPCredentialProvider, which contains also multiOTP inside.
It works with Windows 7/8/8.1/10/11/2012(R2)/2016/2019/2022 in 64 bits.
(https://download.multiotp.net/credential-provider/)
2) During the installation, specify the folder on the client where the
multiotp.exe file and folders must be installed and configured.
3) In the wizard, leave the URL of the multiOTP server(s) empty.
4) You can also choose to require a strong authentication only for RDP.
5) When you are on the test page, open a command prompt in the folder where
multiOTP is now installed and create a new local user as explained above.
6) If the test is successful, the Credential Provider is installed.
7) To disable the Credential Provider, uninstall it from Windows,
or execute multiOTPCredentialProvider-unregister.reg

ADDING 2FA WITH MULTIOTP TO THE REMOTE DESKTOP WEB ACCESS (RDWEB) ON WINDOWS
============================================================================
For these instructions, we assume that multiOTP is installed in the
folder C:\multiOTP
After Remote Desktop Web Access installation, RDWeb files are stored in the
folder C:\Windows\Web\RDWeb\
1) Edit the file C:\Windows\Web\RDWeb\Web.config, and add three lines right after
the appSettings block like this:
```
<?xml version="1.0"?>
<configuration>
<appSettings>
<!-- multiOTP addon begin -->
<add key="MultiOTPPathAndName" value="C:\\multiOTP\\multiotp.exe" />
<add key="OTPUsernameRegex" value="^[0-9a-zA-Z]*$" />
<add key="OTPRegex" value="^[0-9]{6}$" />
<!-- multiOTP addon end -->
...
```
2) Edit the file C:\Windows\Web\RDWeb\Pages\en-US\login.aspx (en-US is for the
american english version of the page), and add three lines here:
```
...
<% @Import Namespace="System.Web.Security.AntiXss" %>
<!-- multiOTP addon begin -->
<% @Import Namespace="System.Diagnostics" %>
<% @Import Namespace="System.Text.RegularExpressions" %>
<% @Import Namespace="System.Configuration" %>
<!-- multiOTP addon end -->
<script language="C#" runat=server>
...
```
3) Always in the same file login.aspx, add this line after Localizable Text:
```
...
// Localizable Text
//
// multiOTP addon begin
const string L_OTPLabel_Text = "OTP:";
// multiOTP addon end
const string L_DomainUserNameLabel_Text = "Domain\\user name:";
...
```
4) Always in the same file login.aspx, at the end of the LoginPageLoadAsync()
method, add this line:
```
...
// multiOTP addon begin
if ( Request.Form["UserOTP"] != null ) Session["UserOTP"] = (string)Request.Form["UserOTP"];
// multiOTP addon end
}
//
// Special case to handle 'ServerConfigChanged' error from Response's Location header.
//
try
...
```
5) Always in the same file login.aspx, replace the method
SafeRedirect(strReturnUrlPage); with the following lines:
```
...
if ( HttpContext.Current.User.Identity.IsAuthenticated == true )
{
// multiOTP addon begin
string strOTPUsername = HttpContext.Current.User.Identity.Name;
if (strOTPUsername.Split('\\').Length > 1) strOTPUsername = strOTPUsername.Split('\\')[1];
if (strOTPUsername.Split('@').Length > 0) strOTPUsername = strOTPUsername.Split('@')[0];
bool bOTPAuthenticated = false;
if (Session["UserOTP"] != null)
{
string strOTP = (string)Session["UserOTP"];
if (!string.IsNullOrEmpty(strOTP) && Regex.Match(strOTP,ConfigurationManager.AppSettings["OTPRegex"]).Success && !string.IsNullOrEmpty(strOTPUsername) && Regex.Match(strOTPUsername,ConfigurationManager.AppSettings["OTPUsernameRegex"]).Success)
{
ProcessStartInfo oOTPStartInfo = new ProcessStartInfo();
oOTPStartInfo.FileName = ConfigurationManager.AppSettings["MultiOTPPathAndName"];
oOTPStartInfo.Arguments = strOTPUsername + " " + strOTP;
oOTPStartInfo.CreateNoWindow = true;
oOTPStartInfo.UseShellExecute = true;
Process oOTP = Process.Start(oOTPStartInfo);
oOTP.WaitForExit();
bOTPAuthenticated = (oOTP.ExitCode == 0);
}
}
if(bOTPAuthenticated)
{
if (String.IsNullOrEmpty(strReturnUrlPage))
Response.Redirect("default.aspx");
else
SafeRedirect(strReturnUrlPage);
}
else
{
FormsAuthentication.SignOut();
bFailedLogon = true;
if (bFailedAuthorization) bFailedAuthorization = false;
}
// multiOTP addon end
// multiOTP remove begin
// SafeRedirect(strReturnUrlPage);
// multiOTP remove end
}
...
```
6) Always in the same file login.aspx, after the "UserPass" input, add the
following lines:
```
...
<label><input id="UserPass" name="UserPass" type="password" class="textInputField" runat="server" size="25" autocomplete="off" /></label>
</td>
</tr>
</table>
</td>
</tr>
<!-- multiOTP addon begin -->
<tr>
<td>
<table width="300" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="130" align="right"><%=L_OTPLabel_Text%></td>
<td width="7"></td>
<td align="right">
<label><input id="UserOTP" name="UserOTP" type="password" class="textInputField" runat="server" size="23" autocomplete="off" /></label>
</td>
</tr>
</table>
</td>
</tr>
<!-- multiOTP addon end -->
...
```
7) Be sure that that the RDWeb Application Pool Account has read/write access
to the installed multiOTP folder and subfolder (C:\multiOTP)
8) In order to have some logs, you will have to enable the log option in the
multiotp.ini (C:\multiOTP\config\multiotp.ini):
```
...
log=1
...
```
9) Be sure to restart IIS on your Windows RDWeb server
SAME WINDOWS GENERIC ACCOUNT WITH MULTIPLE TWO-FACTOR AUTHENTICATION ACCOUNTS
=============================================================================
If you have to share the same generic Windows account, but you still need
2FA authentication for each user (like for a specific industrial computer in a
24/7/365 process), you can do the following configuration:
1) Create (or sync with AD/LDAP) a multiOTP account for the generic account
2) In multiOTP, set the description of the generic account to "multi_account"
(if the account is synced by AD/LDAP, put the description in the AD/LDAP)
3) Create (or sync with AD/LDAP) the accounts of each users
4) On the login screen of the computer, use the following credentials:
- Account : generic Windows account
- Password : password of the generic Windows account
- OTP : [username of the specific user][space][OTP code of the specific user]
USING MULTIOTP ON LINUX FOR SSH LOGIN
=====================================
0) Configure OpenSSH and PAM
Configure your OpenSSH server to request the PassCode (PinCode+OTP)
to the radius server. For this purpose we will use a radius PAM agent.
1) PAM configuration for OpenSSH server:
Edit the file /etc/pam.d/sshd with this configuration.
Comment the username/password line and add the PAM library.
Be sure you have the PAM radius library.
```
#auth required pam_stack.so service=system-auth
auth required /lib/security/pam_radius_auth.so
```
2) Specify the Radius Server.
Create and edit a file called server in /etc/raddb
with the Radius IP,port and the shared secret key.
```
#Server[:port] shared_secret timeout (s)
127.0.0.1 secret 1
10.1.23.1:1812 myfirstpass 6
```
3) OpenSSH server (radiusd daemon) configuration:
Edit /etc/sshd/sshd_config and be sure PAM is
enabled and keyboard-interactive AuthN support.
```
UsePAM yes
PasswordAuthentication no
ChallengeResponseAuthentication yes
```
4) Stop and start the OpenSSH server
```
/etc/init.d/sshd stop
/etc/init.d/sshd start
```
5) You are now ready to test your login SSH with an software OTP :-)

You can now flash the SD (check point 3) and 4) if needed), put the SD Card
into the Raspberry Pi and boot it. You can go directly to point 15)
1) If you want to use a battery backed up Real Time Clock, install it now in your
Raspberry Pi, the drivers for these models are included in the package:
- https://afterthoughtsoftware.com/products/rasclock
- http://www.cjemicros.co.uk/micros/products/rpirtc.shtml
- https://www.robotshop.com/ca/en/elecrow-ds3231-high-precision-rtc-clock-module-raspberry-pi-b.html
- https://learningdevelopments.co.nz/products/rtc-clock-module-for-raspberry-pi
2) Download the last image of Raspbian to be flashed
http://downloads.raspberrypi.org/raspbian_latest (currently 2017-09-07-raspbian-stretch.zip)
3) Format your SD Card using the SD Card Association's formatting tool
https://www.sdcard.org/downloads/formatter_4/
4) Flash the raw image using UNIX tool dd or Win32DiskImager for Windows
(http://sourceforge.net/projects/win32diskimager/files/latest/download).
This should take about 10 minutes.
5) Copy all files from multiotp/raspberry/boot-part to the root of the SD Card
(it could overwrite some files like config.txt)
6) When copy is done, eject the SD Card
7) Connect the Raspberry Pi to the local network
8) Put the SD card into the Raspberry Pi and boot it
9) Login directly on your Raspberry Pi, or using SSH, with the default username "pi" and the password "raspberry"
10) Launch the initial configuration by typing sudo raspi-config
11) Choose the following options
1) Expand Filesystem
2) Change User Password
4) Internationalisation Options (if needed)
8) Advanced Options
A2 Hostname (change the hostname to your favorite name, for example "multiotp")
12) Select Finish and answer "<Yes>" to reboot, ore type "sudo reboot"
13) Login again directly (after about 30 seconds) on your Raspberry Pi, or using SSH, with the default username "pi" and your new password
14) Type "sudo /boot/install.sh"
Everything is done automatically (it will take about 35 minutes) and the Raspberry Pi is rebooted automatically
15) The fixed IP address is set to 192.168.1.44, with a default gateway at 192.168.1.1
To adapt the network configuration, edit the file /etc/network/interfaces
16) Congratulations! You have now an open source and fully OATH compliant
strong two factors authentication server!
Surf on http(s)://192.168.1.44 to use the basic interface (admin / 1234)
17) The default radius secret is set to myfirstpass for the subnet 192.168.0.0/16.
To adapt the freeradius configuration, edit the file /etc/freeradius/clients.conf.
LDAP FILTER CUSTOMIZATION
=========================
You can customize your own LDAP filter. By default, the LDAP filter is empty.
In the LDAP filter, you can use the following placeholders:
{cn_identifier}, {username}, {groups_filtering}
OPENSSL OPTIONS FOR LDAPS
=========================
You can define how the certificate bundle is handled with the ldaptls_reqcert option.
You can define a custom cipher suite with the ldaptls_cipher_suite option.
COMPATIBLE CLIENTS APPLICATIONS AND DEVICES
===========================================
Open source project multiOTPCredentialProvider which is based on MultiotpCPV2RDP
from arcadejust and MultiOneTimePassword Credential Provider from Last Squirrel IT.
It works with Windows 7/8/8.1/10/11/2012(R2)/2016/2019/2022 in 64 bits.
The Credential Provider is using directly a local version of multiOTP which
can be configured as a client of a centralized multiOTP server (with caching support)
(https://github.com/multiOTP/multiOTPCredentialProvider)
Any firewall can connect with the Radius protocol to a multiOTP radius server.
On advanced firewalls like the ZyXEL ZyWALL USG series, you can do some advanced
things like:
- receiving a specific group for each multiOTP user (using the Filter-Id
option). This is very useful to allow specific rules for some groups.
- VPN connections can be set-up to have a strong authentication (X-Auth).
- Strong Web authentication can be combined with specific firewall rules.

MULTIOTP PHP CLASS DOCUMENTATION
================================
Have a look into the source code if you want to know how to use it,
and you may also check multiotp.cli.header.php which implements the class.
MULTIOTP COMMAND LINE TOOL
==========================
```
multiOTP 5.9.7.1 (2023-12-03)
(c) 2010-2023 SysCo systemes de communication sa
http://www.multiOTP.net (you can try the [Donate] button ;-)
multiotp will check if the token of a user is correct, based on a specified
algorithm (currently Mobile-OTP (http://motp.sf.net), OATH/HOTP (RFC 4226)
and OATH/TOTP (RFC 6238) are implemented). PSKC format supported (RFC 6030).
Supported encryption methods are PAP and CHAP.
Yubico OTP format supported (44 bytes long, with prefixed serial number).
SMS-code are supported (current providers: afilnet,aspsms,clickatell,
clickatell2,ecall,intellisms,nexmo,nowsms,smseagle,
smsgateway,swisscom,telnyx,custom,exec).
Specific SMS sender program supported by specifying exec as SMS provider.
Google Authenticator base32_seed tokens must be of n*8 characters.
Google Authenticator TOTP tokens must have a 30 seconds interval.
Available characters in base32 are only ABCDEFGHIJKLMNOPQRSTUVWXYZ234567
To quickly create a user, use the -fastcreate option with the name of the user.
A quickly created user is compatible with Google Auth (30 seconds, 6 digits).
Depending on the prefix PIN option (WHICH IS ENABLED BY DEFAULT), a prefix PIN
will be requested or not before the displayed token.
If the PIN is not given, it is generated randomly.
To quickly create a user without a prefix PIN request, use -fastcreatenopin
To quickly create a user with a prefix PIN request, use -fastecreatewithpin
If a token is locked (return code 24), you have to resync the token to unlock.
Requesting an SMS token (put sms as the password), and typing the received
token correctly will also unlock the token.
The check will return 0 for a correct token, and the other return code means:
Return codes:
0 OK: Token accepted

multiOTP can be combined with a Raspberry Pi (http://www.raspberrypi.org/) in
order to have a very low budget strong authentication device. Please look at
the readme file in order to learn how to set it up in a few steps.
The distribution is already optimized with an HTTP proxy to speed up the CLI.
A ready to use binary image can be downloaded at https://download.multiOTP.net/
multiOTP open source is also available as a ready to use virtual appliance in
standard OVA, VMware optimized or Hyper-V formats.
Virtual appliance images can be downloaded at https://download.multiOTP.net/
