-Catalyst::Plugin::Authentication::Credential::Password - Authenticate a user
-with a password.

-=head1 SYNOPSIS

- use Catalyst qw/
- Authentication
- Authentication::Store::Foo
- Authentication::Credential::Password

+Catalyst::Plugin::Authentication::Credential::Password - Compatibility shim
=head1 DESCRIPTION
-This authentication credential checker takes a user and a password, and tries
-various methods of comparing a password based on what the user supports:
-
-=over 4
-
-=item clear text password
-
-If the user has clear a clear text password it will be compared directly.
-
-=item crypted password
-
-If UNIX crypt hashed passwords are supported, they will be compared using
-perl's builtin C<crypt> function.
+THIS IS A COMPATIBILITY SHIM. It allows old configurations of Catalyst
+Authentication to work without code changes.
-=item hashed password
+B<DO NOT USE IT IN ANY NEW CODE!>
-If the user object supports hashed passwords, they will be used in conjunction
-with L<Digest>.
-
-=back
+Please see L<Catalyst::Authentication::Credential::Password> for more information.
=head1 METHODS
-=over 4
-
-=item login $user, $password
-
-=item login
-
-Try to log a user in.
-
-C<$user> can be an ID or object. If it isa
-L<Catalyst::Plugin::Authentication::User> it will be used as is. Otherwise
-C<< $c->get_user >> is used to retrieve it.
-
-C<$password> is a string.
-
-If C<$user> or C<$password> are not provided the parameters C<login>, C<user>,
-C<username> and C<password>, C<passwd>, C<pass> will be tried instead.
