Yahoo allows sign in to its websites using Facebook or Google IDs

Yahoo is launching third-party user authentication with Facebook and Google logins (via OpenID) across its network of websites. Users of Facebook and Google will be able to sign in and interact on Yahoo! Via their Facebook or Google IDs.

The official statement posted on the company blog says: “By supporting user sign-in to Yahoo! through Facebook and Google, we streamline the Yahoo! user identity creation process and can further personalize user experience across Yahoo! services. Commenting on a Yahoo! News article, playing Yahoo! Fantasy Sports, or interacting with photos on Flickr -- now users can do all this with their existing Facebook or Google IDs. Returning users who are already signed in to Facebook or Google can benefit from the “one-click” sign-in to Yahoo!, no longer required to enter ID and password. You can initiate the “one-click” sign-in simply by clicking on the "Sign in with: Facebook or Google" icon on the Yahoo! login screen. You are then signed in to Yahoo!, ready to participate fully.”

However, the feature has some limitations. Thus, users won’t be able to sign into a mobile or desktop client using a Google OpenID.
