Rails 3 - Use only OpenID authentication

Question

I want to add authentication to my Ruby on Rails 3 app, but I only need users to be able to authenticate using their Google accounts, because I'm making it a hosted app for the Chrome Webstore, so I think OpenID would work well for this. I want to have some custom fields in the user database to store user-specific data. What should I use for this? I want users to be able to sign up only with OpenID. Thanks.

Answer 1

You should try omniauth gem, it uses not only Google OpenID. Omniauth takes user's data from provider and pass to your application which is you can amplify

Answer 2

I've been using authlogic and authlogic-oid add-on to handle this.

Answer 3

You could try the devise_openid_authenticatable gem. I haven't used it myself but it looks like it would do what you want using the Devise authentication gem, which is what I use on all of my Rails projects.
