Exciting stuff–Facebook is rolling out full support for OpenID. Once it’s done being pushed to all users, you’ll be able to log in seamlessly to Facebook if you’re already logged into your OpenID provider.

Combine this with two-factor authentication from PIP, and things are shaping up nicely.

Oh, and they’re supporting seamless logon from Google as well. Very cool stuff. ::
