The bundle dispatches the following events during the authentication process:
scheb_two_factor.authentication.require is dispatched when two-factor authentication is required from the user. This
normally results in a redirect to the two-factor authentication form.
scheb_two_factor.authentication.form is dispatched when the two-factor authentication form is shown.
scheb_two_factor.authentication.require is dispatched when two-factor authentication is required from the user (the
form is shown).
scheb_two_factor.authentication.attempt is dispatched when two-factor authentication is attempted, right before
checking the code.
scheb_two_factor.authentication.success is dispatched when two-factor authentication was successful for a single
provider. That doesn't mean the entire two-factor process is completed.
scheb_two_factor.authentication.failure is dispatched when the given two-factor authentication code was incorrect.
scheb_two_factor.authentication.complete is dispatched when the entire two-factor authentication process was completed
successfully, that means two-factor authentication was successful for all providers and the user is now fully
authenticated.
