What is OpenID?

OpenID is a free Single-Sign-On-System. It replaces the familiar login with username and password on a website.
In order to log in on a website that supports OpenID you just have to enter your OpenID which is a special URL. The website, e.g. sixgroups.com, performs the login in co-operation with an OpenID-Provider.

If you have signed up on Yahoo!, AOL, and others you already own an OpenID. Find out more on their websites.
