This paper proposes a new approach to biometric authentication based on keystroke dynamics in mobile devices. The methodology is easily accessible and can be used by anyone familiar with mobile phones. Users store their information in the system, creating an access account. During password entry, the system tracks the time taken to press and release keys and compares these parameters with stored data. If the patterns match, the user is authenticated; otherwise, access is denied. The study analyzed parameters such as input capture time, individual user models, and ideal thresholds. This approach enhances security, ensuring that even if an impostor knows the password, only the legitimate user can gain access.
