A Comprehensive Survey of Graphical Passwords Authentication Systems that Provides Security

In today's data-driven world, the importance of cybersecurity has grown exponentially. The biggest threat to data can be tampering with the authentication system that is the gateway to digital assets. The aim of this survey is to give a comprehensive overview of all relevant technologies, architectures, processes and literature. This research study discusses about the various dimensions of a graphical authentication system, including privacy, threat detection and access control mitigation, encryption, and user awareness. Authentication system graphics proved to be an innovative alternative to traditional alphanumeric passwords to improve user security and convenience. Dive into knowledge-based authentication, which includes picture passwords that are said to be more convenient for humans to remember passwords. This survey provides a comprehensive overview of the underlying concepts, implementation techniques, challenges, types and potential future reach of the graphic passwords. In addition to discussing the benefits, it also discusses the security, usability, privacy, and implementation challenges of these methods.
