Abstract - Graphical password authentication (GPA) is an alternative to traditional text-based passwords that uses images, patterns, or other visual elements as password input. In this paper, we propose a new GPA system that enhances security while maintaining usability. Our proposed system combines randomization and obfuscation techniques to prevent shoulder surfing attacks and other forms of password guessing. We evaluated our system using a user study and compared it with existing GPA systems. The results showed that our proposed system outperformed the existing systems in terms of security and usability.

Key words: Graphical password authentication, randomization, obfuscation, security, usability.
