We have highly flexible support for 2FA (Two-factor authentication). It can be activated for individual users, all users, all administrators, only for an organization, and so on. All users with a phone number will receive an SMS when they attempt to log in. If the field is empty, they will receive an email instead.
If you are interested in activating 2FA, please contact support@learnifier.com and state for whom you wish to activate it for.
