Question

I want my users to be able to login to my page at least via Facebook, Twitter, Google, Yahoo and OpenID. Is there already something out there which does this?

Answer 2

Is not what you are looking for, but with OpenInviter, you can know if the user insert a valid login username / password

Answer 3

A google search of OpenID API and Facebook Login API should cover two of those, though i dont know how well they will all interact with eachother

PHP OpenID Library that allows facebook / openid / twitter, etc;

Does that help?
