OpenID 2.0 Finally Released

5th Dec 2007

After almost two years in development, OpenID Authentication 2.0 has been announced as final at IIW this morning.

This is excellent news. Hopefully it won't take too long for everyone to update their existing 1.1 implementations and we can start to feel the benefits. The IPR situation is now straight as well, meaning that bigger players such as Microsoft and Yahoo! should soon be able to come to the table properly.

Also part of this announcement is OpenID Attribute Exchange, which I don't know much about but it would seem to have a lot of potential as a platform for future projects. It'll be interesting to see what people do with it.
