• It show on usual Dolibarr login page a third text input control to put a TOTP 6-digit code.
• This 3rd control must be populated by users which have enabled this Two Factor (2FA) system.
• So it is a 6-digit code optional: some users can have it enabled but others not.
• Only is possible to enable the 2FA by the same user. Admin users cannot do it.
• Admin users (or users with assigned permissions over other users) can ONLY know which other users has enabled the 2FA and disable it.
• The only one who can see the TOTP secret key is the corresponding user.
• The module always show to the user its secret key and the QR code to be scanned by a mobile app.
• When activating 2FA for your user you can set manually your secret TOTP key, specially useful to administer several Dolibarr instances.
• You can let the administrators users to SEE and/or ACTIVATE the 2FA seed for other users, or not.
• You can to set it to be MANDATORY to activate 2FA for ALL users, and you can define a grace period of X days after create a new user, and also can set a deadline to ALLOW ACCESS for users without 2FA enabled.
• Furthermore, you can allow access outside the grace period, as long as the user has defined a valid email address, where they will receive a random 6-digit code each time they want to access.
