What is OpenID?
OpenID is a new way to identify yourself all over the web. With your own personal OpenID you can login to any OpenID-enabled site (there are over 1,000 of them and that number is growing everyday) and identify yourself as you.
It’s one username and one password for all of the sites that you go to. It means no more registration screens on the sites you go to. Most importantly, OpenID is open; its a protocol that has been developed by a diverse community interested in solving the identity problem once-and-for-all. You can use it at any website that is OpenID enabled as if you already had an account. It blurs the lines of where you you have an account, and the question you ask changes from “Do I have an account?” to “Is the site OpenID enabled?”
