I think I should noted down two gems that I mentioned in my talk.
- Omniauth — a middleware that help you authenticate user to various SSO sites, such as Facebook Connect, Twitter, Google Account
- Devise — fully-functional authentication system. If you write an app that need authentication, this should be the solution for you. Writing your own authentication is discourage now. More on this later.
I feel like I was saying 3 of them, but I can’t remember the other one. Anyway, don’t forget to dig into RubyGems to find out some great gem to use in your project.
