As promised, Yahoo has launched its new OpenID provider service. Yahoo’s 248 million worldwide users now have a way to login to any site that supports OpenID. To get started, just head over to the new OpenID page and set up your OpenID preferences.
To use your newfound OpenID powers, check out the ever-expanding list of OpenID consumer sites — Ma.gnolia, Technorati and Blogger are just a few of the places where you no longer need to worry about remembering your username/password combo.
At the moment, Yahoo is an OpenID provider, not a consumer, which means that those of us who already have OpenIDs still can’t use them to login to Yahoo services. But even if Yahoo’s OpenID support is disappointingly one-way, it triples the number of potential users. Yahoo’s OpenID support will likely drive not just adoption among other sites, but also other potential OpenID provider services from the likes of Google, Microsoft and more, which will now be feeling greater pressure to support the decentralized identity system.
