Do something just after symfony2 login success and before redirect?

Question

I\'m searching for a while now, for any info, on how to do something after authentication success in symfony2. I want to rehash user password to use bcrypt just after succes

You can specify a login success handler to be executed on successful login.

For example, your security.yml

firewalls:
    main:
        pattern: ^/
        form_login:
            success_handler: my.security.login_handler

Now create the class which implements Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface and on successful login, you can do whatever you need and handle the redirect as you see fit.

/**
 * 
 */
public function onAuthenticationSuccess(Request $request, TokenInterface $token)
{
    // handle it and return a response
}

Then create a service with that name in your services.xml for your bundle, or in your config.yml using the newly created handler.

I originally found out how to do this following this tutorial:
