Question from the Symfony 3 test

Allows to centralize and standardize the authentication steps in a single class that implements the GuardAuthenticatorInterface interface.

Does not allow to exploit the user's memory feature: Remember me .

The CustomAuthenticationException class allows you to customize the message of an exception thrown during one of the authentication steps.

During authentication, the first method called is checkCredentials().

Several authentication methods (form, token, ...) are usable in a “GuardAuthenticatorInterface” class.
