[Catalyst] C::P::Authentication, force user authentication

[David Schmidt]

Hello

When a user lost his password I send a digest by email.
If he enters this digest I want to automatically authenticate the user
so he can edit his password.

I only found this method but it says in the docs you shouldn't use it
in your code as it is an internal function only.
$c->set_authenticated( $user, $realmname )

Any other way to force user authentication?

thanks
