Abstract— Traditional login systems mainly depend on passwords to verify users, but this approach often creates several security risks. Passwords can be easily guessed, reused across different platforms, or stolen through phishing and brute-force attacks, which may lead to unauthorized access. To address these issues, this paper introduces a Next-Generation Touchless Authentication system that uses QR code technology and Time-Based One-Time Passwords (TOTP) to provide a safer and more convenient login process. In this method, users first confirm their identity through email verification, after which they can access the system without using a traditional password. Instead, authentication is completed using a one-time password generated by an authenticator application. To ensure reliability, the system also provides a backup secret key that allows users to recover their account if they lose access to the authenticator device. This approach improves both security and user convenience by eliminating passwords while maintaining a reliable authentication mechanism.
