Symfony force login and remember me

Question

Following code will force login user automatically and it works fine. I want to add remember me functionality. So when we force login user and then also add remember me, so next time he automatically login to the site.

// Auto Authenticate User
        $firewall = 'user_firewall';
        $token = new UsernamePasswordToken($user, null, $firewall, $user->getRoles());
        $this->get('security.token_storage')->setToken($token);

        $session = $this->get('session');
        $session->set('_security_'.$firewall, serialize($token));
        $session->save();

Answer 1

Use RemeberMeToken and there is no need to set it manually in session, just fire interactive_login event:

// Auto Authenticate User
$firewall = 'user_firewall';
$key = $this->getParameter('secret'); //from parameters.yml
$token = new RememberMeToken($user, $firewall, $key);
$this->get('security.token_storage')->setToken($token);

$this->get('event_dispatcher')->dispatch(
    SecurityEvents::INTERACTIVE_LOGIN,
    new InteractiveLoginEvent($request, $token)
);

EDIT: add this to your security.yml:

        yourProviderKey: # oauth i guess
            remember_me: true
        remember_me:
            secret:   '%secret%'
            lifetime: 604800 # 1 week in seconds
            path:     /
            #always_remember_me: true # optional

If this will not work, try to add ?_remember_me=1 to the end of your check_path.
