I am looking to allow users to register and login using their social network accounts from:
- yahoo
- aol
- etc
OpenID seems like a good option but it doesn't appear that Facebook or Twitter support it which kind of makes it useless. Any suggestions on a free (for large sites) option? OAuth seems good, but isn't that going to require the user to authenticate everytime? I want something more automated so they click 'twitter' and if they are logged in on twitter and have already granted authorization, they get automatically logged in on our site. I can handle the work on my site and have no probelm working with apis.
Thanks!
