I am making security system using symfony4 built-in security system.

I integerate registration form on index page.

And handle registration in function index

However after finishing registration, user needs to type username and passwrd again.

I want to skip this process.

After registration, User don't need to type username and password again.

How can I solve this??

public function index(Request $request, UserPasswordEncoderInterface $passwordEncoder)

    {

        $this->commonFunc = $commonFunc;



        $this->data['user'] = $this->getUser();



        if (!$this->data['user']){// make registration form when no login

            $user = new User();

            $form = $this->createForm(UserType::class, $user);



            $form->handleRequest($request);



            if ($form->isSubmitted() && $form->isValid()) {



                $password = $passwordEncoder->encodePassword($user, $user->getPlainPassword());

                $user->setPassword($password);



                // save the User!

                $entityManager = $this->getDoctrine()->getManager();

                $entityManager->persist($user);

                $entityManager->flush();

                $this->data['user'] = $user;



                // After registration process. the user must input id and pass again.

                // I want to skip this.





                return $this->redirectToRoute('index');



            }

            $this->data['form'] = $form->createView();

        }



        return $this->render('default/index.html.twig', [

            'controller_name' => 'DefaultController',

            'data' => $this->data

        ]);

    }

These are my final code from @Cerad suggestion.

I changed the way to get tokenStorage(my environment is 4.1)
Somehow, I don't need to do event dispatch...
However it works.

    $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());

// $this->tokenStorage->setToken($token);
$this->get('security.token_storage')->setToken($token);

Here is what I use:

private function loginUser(Request $request, UserInterface $user) : void

{

    $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());

    $this->tokenStorage->setToken($token);



    $event = new InteractiveLoginEvent($request, $token);

    $this->eventDispatcher->dispatch(SecurityEvents::INTERACTIVE_LOGIN, $event);

}

You can either inject the token storage and event dispatcher or pull them from the container.
