Abstract: “Login is the basic and primary stage of authentication to any system. For Login users create memorable passwords, so that they remember those passwords when they next need access to the system Users create their own passwords as system generated passwords are difficult to remember. Going with same fact such text based factors are vulnerable to many well known attacks. So an alternative method was designed that used Graphical Passwords that use images or representation of Images as passwords. There are various graphical password schemes and software’s in market. Text based passwords are mercilessly broken down so to mitigate the issues with the old methods advanced techniques have been proposed using Graphical Passwords. This paper aims at providing a comparative study of the various advance graphical password techniques available and I have also proposed a system using Cued Click Point Based Authentication for tightening the authentication process of any Online Application.”
