You can find the code for AG Auth here and the user guide is available from here

The Auth Library is a small but powerful authentication library for CodeIgniter.

Features:-

—Login (using username or email)
—Logout
—Register
—Secure Remember me (essentially unbreakable)
—Strong username and password policy server side
—Maximum number of failed login attempts, security against DDoS or Bruteforce attacks
—Makes use of the form validation class

The best thing about The Auth Library is that you don’t need to write any code to use it. Period. You use the Auth Library by extending the controller Application instead of Controller.
