Today Yahoo! announced it has joined OpenID, in one fell swoop
legitimizing it as a universal Internet login method, as well as
tripling the number of OpenID accounts.
Yahoo!'s initial OpenID service, which will be available in public beta on January 30, enables a seamless and transparent web experience by allowing users to use their custom OpenID identifier on me.yahoo.com or to simply type in "www.yahoo.com" or "www.flickr.com" on any site that supports OpenID 2.0. Alternatively, web sites that accept OpenID 2.0 will be able to add a simple "Sign-in with Your Yahoo! ID" button to their login pages that will make it even easier for their users. Yahoo! is working with several partners, including Plaxo and JanRain, to make it possible for users to access these sites with their Yahoo! ID from the first day of the public beta.
"A Yahoo! ID is one of the most recognizable and useful accounts to have on the Internet and with our support of OpenID, it will become even more powerful," said Ash Patel, executive vice president of platforms and infrastructure at Yahoo!. "Supporting OpenID gives our users the freedom to leverage their Yahoo! ID both on and off the Yahoo! network, reducing the number of usernames and passwords they need to remember and offering a single, trusted partner for managing their online identity."
Great breakthrough for OpenID. Now if they can just get some other large sites to sign on (Google, anyone?).
