Using Google, Yahoo, Twitter for registration

Question

Hello, thanks for the Question2Answer platform.

I can see that's it's possible for users to register/login using their facebook accounts which is cool since users won't have another set of usernames and passwords to remember. 

In the same line, since not all are on  facebook, is there a plugin or soorts that enables new users to register using their existing Google, Yahoo and Twitter accounts? This ofcourse doesn't take away the default registration form. 

Thanks
