ABSTRACT

A security breach can put national secret data, as well as the private information of an organization or a person, at risk. Text-based passwords are the most common type of security password. However, these passwords are readily cracked, and one's personal information might fall into the wrong hands. Security issues connected to logins and accesses have become a key concern as cyber-crime has increased. Furthermore, just a single security authentication method is insufficient to keep you safe from cyber-attacks. As a result, in order to improve security, we created a Three-Level Password Authentication system that ensures that only authorized users have access to the system or data. This system has three levels of logins, each with three separate password methods. A text-based password, image-based segmentation password, and graphical password are included in the project. With each level, the password difficulty rises, making access more secure. This PHP-based Three Level Authentication System will assist customers to protect their data from hackers and cyber dangers in this way. Users will be requested to create three-level passwords upon user registration in this system for security reasons. The first level is the text-based password system, the second level is the image-based password system, and the third level is the graphical password technique. Users must log in to check the security of the system by submitting a three-level password authentication. As users begin to submit passwords, the first level will authenticate the user by matching the data recorded in the database upon registration, and the second and third levels will authenticate the password supplied by the user, respectively.
