Simple logic store a token everytime the user login to the database and store d copy of the token to the active session. In case he login in somewhere else the token will be overwritten and if mis matches log of the user.
It a simple trick.

I would say it is even simpler than that. As soon as you log in it sets a flag is_logged_in to true, and if you try again from wherever it checks against this flag before allowing you to go any further, i.e setting session data etc.

I don't get the implementation.
Where do we set a flag is_logged_in?

@kenjis , I think he ment set a session flag is_logged_in when the user logins into the system.
