New in OpenID 2.0 is the concept of Directed Identity, in which a user can just specify their OpenID Provider, rather than having to type in their entire OpenID URL. Users can just type in yahoo.com or flickr.com to initiate the Sign-in process. In order to optimize this experience, we provide special buttons that Yahoo! users can click on to sign in. Clicking on the Yahoo! Sign-in button auto-fills and submits yahoo.com on the OpenID sign-in form.
