[make:registration] No Guard authenticators found - New Authenticator

[seb-jean]

Hi,
I have Symfony 5.3.2.
I do : php bin/console make:registration-form.

I answered question 'yes' for this question Do you want to automatically authenticate the user after registration? (yes/no) [yes]:.

And I have ! [NOTE] No Guard authenticators found - so your user won't be automatically authenticated after registering..

Did you run make:auth to create the Authentication skeleton before running make:registration-form? In lieu of make:auth, you are able to manually implement your authentication system by following https://symfony.com/doc/current/security.html

[seb-jean]

Yes, I ran make:auth.

[jrushlow]

can you create a simple reproducer app in a public repo?

[seb-jean]

Sure : https://github.com/seb-jean/sftest

I am using Symfony 5.3.2 and have also received the same error ! [NOTE] No Guard authenticators found - so your user won't be automatically authenticated after registering..

After adding symfony/security-guard I am no longer getting that error. However, the logic that gets created with make:registration-form doesn't contain anything to authenticate the user after registration.

[apphancer]

The symfony/security-guard does fix the error message when running the command. However, this package is actually not required as it contains deprecated methods not compatible with Symfony's new Authenticator.

I believe the missing logic is the following:

use App\Security\AppAuthenticator;
use Symfony\Component\Security\Http\Authentication\UserAuthenticatorInterface;
...

public function register(Request $request, AppAuthenticator $appAuthenticator, UserAuthenticatorInterface $userAuthenticator) {
...
if ($form->isSubmitted() && $form->isValid()) {
...
return $userAuthenticator->authenticateUser($user, $appAuthenticator, $request);
}
....
}

Where AppAuthenticator is the class compatible with AuthenticatorInterface.

I can confirme this happens when make:auth creates an authenticator using the new system instead of the old GuardAuthenticator - every time
tryed it several times on newly created projects of symfony 5.4

It also uses UserPasswordEncoderInterface which appears to have been marked deprecated as of Symfony 5.3

small correction to what @apphancer posted:

use App\Security\AppAuthenticator;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
use Symfony\Component\Security\Http\Authentication\UserAuthenticatorInterface;
...
public function register(Request $request, AppAuthenticator $appAuthenticator, UserAuthenticatorInterface $userAuthenticator, UserPasswordHasherInterface $passwordHasher): Response
{
...
if ($form->isSubmitted() && $form->isValid()) {
            // encode the plain password
            $user->setPassword(
                $passwordHasher->hashPassword(
                    $user,
                    $form->get('plainPassword')->getData()
                )
            );
...
return $userAuthenticator->authenticateUser($user, $appAuthenticator, $request);
}
....
}

And remove the use for the old PasswordEncoder
