Graphical authentication is more efficient and more securable. An important usability goal for knowledge based authentication systems is to support user in selecting passwords for higher security in the sense of being from an expanded effective security space. Here, the authors are using x and y coordinates to choose a picture password. Additionally the pictures in x and y coordinates are changing randomly and hence it is difficult to find the original picture. In their base paper the approaches used are "Persuasive cued click points", "Cued click points" and "Pass points".
