Facebook announced that users would soon be able to login to the site via OpenID. Today, Facebook has officially become an OpenID relying party: users can now register for Facebook using their Gmail accounts and any OpenID provider that supports automatic login. As such, Facebook has become the largest OpenID relying party on the web.
Now, once users link their Facebook account to a Gmail address (or OpenID URL), they’ll be automatically logged in when they go to Facebook after having logged into that service. Facebook says that in its user testing so far, users who register through OpenID actually get engaged with Facebook more quickly than others.
