Graphical Authentication Systems are a potential replacement or supplement for conventional authentication systems. Several studies have suggested graphical authentication may offer greater resistance to guessing and capture attacks but there are other attacks against graphical authentication including social engineering, brute force attacks, shoulder surfing, intercepted communication and spyware. In this paper we give a brief description and classification of different graphical password schemes followed by information about vulnerabilities in the various schemes and recommendations for future development.
