# multiOTP package - Strong two-factor authentication open source package
# https://www.multiotp.net/
#
# The multiOTP package is the lightest package available that provides so many
# strong authentication functionalities and goodies, and best of all, for anyone
# that is interested about security issues, it's a fully open source solution!
#
# This package is the result of a *LOT* of work. If you are happy using this
# package, [Donation] are always welcome to support this project.
# Please check https://www.multiotp.net/ and you will find the magic button ;-)
