Two-Factor Authentication Methods
The bundle supports the following authentication methods out of the box:
The Authentication Process with Two-Factor Authentication
What changes when you add two-factor authentication to your application?
The bundle hooks into the security layer and listens for authentication events. When a user login appears and the user has two-factor authentication enabled, access and privileges are temporarily withheld, putting the authentication status into an intermediate state. The user is challenged to enter a valid two-factor authentication code. Only when that code is entered correctly, the associated roles are granted.
To represent the state between login and a valid two-factor code being entered, the bundle introduces the role-like
attribute IS_AUTHENTICATED_2FA_IN_PROGRESS, which can be used in is_granted() calls. IS_AUTHENTICATED_FULLY
is – just like roles – withheld until the two-factor authentication step has been completed successfully.
