OpenID starts with the concept that anyone can identify themselves on the Internet the same way websites do - with a URI. Since URIs are at the very core of Web architecture, they provide a solid foundation for user-centric identity.The first piece of the OpenID framework is authentication -- how you prove ownership of a URI. Today, websites require usernames and passwords to login, which means that many people use the same password everywhere. With OpenID Authentication, your username is your URI, and your password (or other credentials) stays safely stored on your OpenID Provider (which you can run yourself, or use a third-party OpenID "identity provider" (IdP)).
OpenID is increasingly gaining adoption among large sites, with organizations like Google, Microsoft,IBM,Verisign,Yahoo,AOL and Orange acting as providers. In addition, integrated OpenID support has been made a high priority in FIREFOX 3 and OpenID can be used with Windows CardSpace.

As Brad Fitzpatrick (the father of OpenID) said,
“Nobody should own this. Nobody’s planning on making any money from this. The goal is to release every part of this under the most liberal licenses possible, so there’s no money or licensing or registering required to play. It benefits the community as a whole if something like this exists, and we’re all a part of the community.”Links to Check ::
