Sure. You can use session cookie, which will be blown away when the user agent is closed.

Think about it, use session cookie (create a session cookie as session id), together with login id and IP address. To resolve your particular problem: if the same user login from the same IP address with no session id, just clear up his previous sessin context from the server, and let him login.
