How to prevent automatic logout for users in symfony?

@lily 

One way to prevent automatic logout for users in Symfony is to increase the session timeout. You can do this by setting the cookie lifetime to a longer period in your config/packages/framework.yaml file:

1
2
3

framework:
    session:
        cookie_lifetime: 3600 # 1 hour

You can also prevent automatic logout by periodically refreshing the user's session when they interact with your application. You can do this by updating the session every time a user makes a request, for example by calling the $session->migrate() method in your controllers:

1
2
3
4
5
6
7
8
9

use SymfonyComponentHttpFoundationSessionSessionInterface;

public function exampleController(SessionInterface $session)
{
    // refresh the session
    $session->migrate();

    // your controller logic
}

Additionally, you can disable the automatic logout feature entirely by setting the invalidate_session_on_new_login option to false in your security.yaml file:

1
2
3
4
5
6
7

security:
    firewalls:
        main:
            remember_me:
                secret: '%kernel.secret%'
                lifetime: 604800 # 1 week
            invalidate_session_on_new_login: false

By increasing the session timeout, periodically refreshing the session, or disabling the automatic logout feature, you can prevent users from being automatically logged out of your Symfony application.
