Rails 3 multiple accounts authentication solution

I am searching for a working solution of authentication on Rails 3 with the following features:

• account types: standard login, fa开发者_如何学运维cebook connect, openid, oauth

• one user may have (and link) multiple accounts (EG a user attach both Wordpress and Google OpenID accounts)

A working example of Rails app implementing them would be perfect.

You could take a look at devise even thought it doesn't have every feature that you're asking for. But then again I doubt there's something out there doing all that.

Sounds like https://www.ruby-toolbox.com/gems/socialite is hoping to be what you're looking for.
