Does Rails have a built-in authentication system?

Question

I have implemented authentication systems for webapps several times over the years, but before I do it once more, I thought I'd ask if there's a canned solution I should know about.

Last time I checked, there was no built-in Rails authentication system and the standard solution was the restful-authentication plugin. Is that still the case? Or perhaps it's been folded into Rails itself by now? I've seen that happen.

Answer 1

Restful-authentication is still the standard. If you haven't look at the plugin for a while, the source has moved to Github

Answer 2

I'd now suggest AuthLogic instead of restful-auth, it is far less intrusive but less supported (restful-auth is included in things like bort).
