Yahoo supports OpenID, which is the appropriate method for signing in on Yahoo. For Facebook, you can do it yourself (http://developers.facebook.com/docs/authentication/) or use the JS SDK, which makes it as simple as having to read a signed cookie (make sure to validate the signature). JS examples for auth can be found here: http://fbrell.com/auth/all-in-one.
