Today, everyone uses the internet as a common medium for communication. The risk to the multimedia data that we transfer from one end to the other end increases as internet usage increases. Passwords are one of the widely used methods for secured communication. Every kind of global communication uses a password as a means of authentication. The most well-known technique is to utilize a text-based password. The enhancement to the existing text-based password is to use multi-level graphical password authentication provides an alternative to traditional text-based passwords, addressing their limitations. With graphical passwords, users can select images, patterns, or gestures as their authentication method. This approach enhances memorability as humans tend to remember visual cues better than complex alphanumeric passwords. It also improves security by increasing the search space and resistance to dictionary-based and brute-force attacks. Graphical passwords offer a user-friendly and inclusive experience, catering to individuals with difficulty remembering text-based passwords or visual impairments.
