Auth identifier

By default, MembersBundle will use the userName field from your Users entity. If you want to use the email field instead, you need to tell it like this:

members:
    user:
        auth_identifier: 'email' # can be "username" (default) or "email"

Auth Identifier only for registration

You're able to define if your registration form should only contain the auth_identifier field (optional). If only_auth_identifier_registration is set to true (false by default) and members.user.auth_identifier is set to email for example, the registration form type will only show up with email and password fields. By default email, password and password fields are required for registration form.

Attention! If you're using username as only registration field, your user entity won't provide an email address! Keep that in mind when it comes to confirming users profile!
