Most applications out there require you to sign up. As a user, you can sign up for a service, log in, and log out when you’re done. As a creator of a web app, you probably don’t want every user to have access to every single part of the app—like customer details, security information, raw data—so you’ll want to restrict access. Rails: Authentication teaches you how to do this within a Rails application.
