Abstract
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.

Summary
Computer security is a critical issue with modern information systems because its valuable contents and diverse day-to-day applications, namely banking, accounting and others. Obasan Adebola et al / American Journal of Applied Sciences 11 (7): 1065-1069, 2014 phishing, eavesdropping, shoulder surfing and other threats (Bonneau, 2012; Forget et al, 2010; Hafiz et al, 2008; Owens and Matthews, 2008) Another easy method that can be used to restrict access of information to the legitimate users through knowledge-based authentication mechanism which does not require additional hardware is graphical passwords where pictures are drawn via mouse or stylus to register passwords instead of texts to lessen the passwords being forgotten. A user can only be authenticated if correct regions are clicked at later stage
