You can also do this solution if you want to just check once:

There is an event triggered each time there's a successful login being done. The event is named:

security.interactive_login

In order to subscribe to this event, you have to create a service container with your created class let's say "LoginListener.php" and inject the tag "kernel.even_listener" with the event "security.interactive_login":

in LoginListener:

use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;

public function onLoginSuccess(InteractiveLoginEvent $event) {
   if ($this->_security->isGranted('IS_AUTHENTICATED_FULLY')) {
      //your code here...
   }
}

you can also add other dependencies and inject it to the constructor, in my case I had to inject security, session and container:

public function __construct(SecurityContext $security, Session $session,            ContainerInterface $container) {

}
