Password authentication has become a widely recognized element of computer security practices where human users are proven or confirmed as legitimate users for access to secure systems. Using this system, every user needs to recall its password correctly before access can be granted to an intended services or applications. Remembering the secure passwords is an everyday problem for users because of individual memory limitation. In an effort to solve this problem, graphical password was presented as one promising athentication alternative taking advantage of picture superiority over texts. The main objective of this study is to provide a comprehensive survey of array of graphical password schemes in different categories based on their common features with the primary aim of identifying the memorability features and propose a new graphical authentication system with enhanced memorability features.
