Web Based Graphical Password Authentication System is a web based application that can be used in any system to allow users to sign up and log in using a different model other than the static passwords. In normal authentication systems, static passwords are used by users to get in the system but it is a known fact that static passwords are very easy to hack. Thus in this system, a user can select certain points in an image and use them as their password. They are immune to basic hacking techniques like brute force attack & dictionary attacks.
