Abstract

Text-based password is commonly used in user authentication. Due to its complexity, users are having trouble remembering their password combination. An alternative was introduced by Blonder in 1996, called graphical password which was easier to remember because of its graphical content. Therefore usability and memorability are improved. In this paper, we propose and develop a new graphical password called Pass-Coob (Pass color and object), which uses colors and object to authenticate user for improving the security and usability aspects.
