Lately I got many user on my site.

And I really want them to re-login using there password

so how can I clear there password saved "cookie", and force them back to the login page?

You could empty the sessions table using phpmyadmin, but I don't really see the point.

You could as well change your cookie name. This would force everyone to log in once more - it would be the same as if you were deleting all your user's cookies. Make sure to use a valid cookie name (no dots or similar invalid characters). As Nibbler suggested though: it's very hard to understand what you're trying to accomplish and what should be the benefit except annoying your users.

The login cookie does not use the cookie prefix, so that won't work.
