Today, most Internet applications still uses traditional text based passwords for the authentication. Two conflict cases of traditional password i.e. if user choose simple password it will easy to guess by attacker. The other hand, if a password is strong then it is often hard to remember for user. Instead of a text password user will be choose graphical password scheme that uses MD5. In MD5 images that converted into binary code. Here binary code will be the password for user. Thus, graphical password is secure than existing graphical password techniques because every time user needs to enter different set of code for authentication i.e. every time new password gets generated making Dictionary attacks, Brute Force attack, and other attacks infeasible. Because of these advantages, there is a growing interest in graphical password. In addition user can use ?document sharing? feature after authentication process and also graphical passwords can be applied to workstation, web log-in applications, ATM machines and mobile device
