I am newbie to Play 2 framework. I came across to SECURESOCIAL login system, but on it's github site, it is mentioned that it currently doesn't support YAHOO and LINKEDIN. Can some one guide me better solution.
You can take a look at this other module: play-authenticate
But you'll have to write your own providers for Yahoo and LinkedIn.
Yahoo uses a OpenID 2.0 method, a doc can be found here.
LinkedIn uses a Oauth 1.0a method (such as Twitter), a doc can be found here.
