Passwords provide security mechanism for authentication and protection services against unwanted access to resources. The most common and convenient authentication method in use is the alphanumeric password. However, its inherent defect led to the development of graphical password as an alternative. Graphical password which uses images as passwords, rather than alphanumeric characters is motivated particularly by the fact that it is generally easier for users to remember and recall images than words. In this presentation, a study of various schemes of graphical user authentication is presented and also several challenges in graphical authentication are discussed.
