Hello. Im learning Rails by building apps.

I want to make my first authenticated app: users signup, login, do some changes in models they have access to and logout.

I did the Google search but it is quite confusing: many plugins, many tutorials. Don't know where to start.

Is there a state-of-the-art authentication method for Rails? What do you use in Production to authenticate your users?

Any help in this will be helpful. Thanks
