This thesis explores an innovative approach to password generation using a visual and interactive grid system. The proposed system enables users to create complex passwords by interacting with a 4 x 4 grid of cells, where each cell can be colored, annotated with text, and rotated. This method leverages visual memory and spatial reasoning to enhance password complexity and user recall, addressing common security challenges associated with traditional alphanumeric passwords. Implemented using the Flutter framework, the system is evaluated for both security and usability, demonstrating significant improvements in password strength and user satisfaction compared to traditional password generation methods.
