Re: [Rails] What is your favourite authentication gem and why?

Authentication is "are you who you say you are". It establishes a session with the browser, and uses a login to check credentials before allowing that session to see anything you've protected from public view. Authorization uses a method like you describe, which allows certain _authenticated_ people to do certain things. You can't have authorization without authentication -- they build on one another. But they solve different problems than one another.
