How to link a facebook account to a website/blog account

Does anybody know if there exists any way to link a websit/blog account with a facebook account?? What I pretend is that all users in my web are able to publish their comments in my web and in their facebook's wall at the same time without need to log in facebook each time.

As Twitter returns a token when you log in to it so that you can post without twitter login each day. Is that possible with facebook too?
