Copy from http://www.jaspan.com:80/improved_persistent_login_cookie_best_practice

Charles Miller's article, "Persistent Login Cookie Best Practice,"[1] describes a relatively secure approach to implementing the familiar "Remember Me" option for web sites. In this article, I propose an improvement that retains all the benefits of that approach but also makes it possible to detect when a persistent login cookie has been stolen and used by an attacker.

Review

To summarize Miller's design:

When the user successfully logs in with Remember Me checked, a login cookie is issued in addition to the standard session management cookie.[2] The login cookie contains the user's username and a random number (the "token" from here on) from a suitably large space. The username and token are stored as a pair in a database table.
