Authentication is the first step of information security. Authentication schemes require users to memorize the passwords and recall them during log-in time. Traditional text-based authentication schemes have memorability problems for secure passwords. Graphical password schemes are introduced as alternatives to text based schemes. Many techniques have been designed using single image or multiple images. Few grid based authentication techniques are proposed. This paper introduces a new authentication technique based on a well known tool. The most popular game especially in rural areas, “Snakes and Ladders” is used as a tool in authentication technique. The usage of this tool increases the memorability and usability of passwords.
