Laravel 10 Fortify disable automatic login in after registration

@stijndh Do this in your RegisterResponse in your Fortify actions

 public function toResponse($request)
    {
        $this->guard->logout(); // logs out the session
        session()->flash('success', 'We sent a verification code to you. Please verify your email to access your account.');

        return $request->wantsJson()
            ? new JsonResponse('', 201)
            : redirect()->route('login');
    }

Then in your FortifyServiceProvider, add this

  // Prevent Laravel auto login
     app()->singleton(
            \Laravel\Fortify\Contracts\RegisterResponse::class,
            \App\Actions\Fortify\RegisterResponse::class,
        );

@Atoagustyn Thank you so much for your help!

Based on your answer and some more research I was able to make it work. I added RegisterResponse.php in app/Http/Responses (I made a change to the logout code, because I got an error saying Guard didn't exist in RegisterResponse

    use Illuminate\Support\Facades\Auth;

    public function toResponse($request)
    {
      	Auth::guard('web')->logout();
      	
      	session()->flash('status', 'message');
      
        return $request->wantsJson()
                    ? new JsonResponse('', 201)
                    : redirect()->route('login');
    }

And in my FortifyServiceProvider I added the following in the boot:

        app()->singleton(
              \Laravel\Fortify\Contracts\RegisterResponse::class,
          	  \App\Http\Responses\RegisterResponse::class
          );

@stijndh This was my solution in laravel 11. Go to the FortifyServiceProvider class, and in the startup method, type the following.

$this->app->instance(RegisterResponse::class, new class($this->app->make(StatefulGuard::class)) implements RegisterResponse { private $guard;

public function __construct(StatefulGuard $guard)
{
    $this->guard = $guard;
}

public function toResponse($request)
{
    $this->guard->logout();
    return Redirect::route('login');
}

});
