I have a web application where I need to make sure authentication credentials are not shared among multiple individuals. What techniques are available within the framework that have proven successful in detecting shared credential use and prevented re-use of a single username and password?

Track a login session for each user in the database. If another user attempts to login and the session is already open, deny access (with a message).

Make sure to call your logout procedure which will close the session on the Session_End event.
