A3M sounds like something you could use. It has normal user authentication, facebook, twitter, google, yahoo and openid.
Give it a try to see if it has what you need.

I want to make a "sign in with twitter /facebook" web apps with codeigniter . It seems everybody suggest me to use https://github.com/philsturgeon/codeigniter-oauth2 library.
Is there any complete tutorial using that library ? or any alternative library with complete tutorial to use it?
