QR Code-Based Authentication System Inspiration The inspiration behind this project came from the increasing need for secure yet user-friendly authentication methods. Traditional password-based logins are often compromised due to phishing, weak passwords, and brute-force attacks. I wanted to build a system that eliminates these risks while making authentication fast, simple, and secure. QR codes offer a seamless way to log in without the need to remember complex passwords.
What I Learned Throughout this project, I learned about QR code generation, user authentication, and database management using SQLite. I also explored how businesses implement passwordless authentication and discovered ways to enhance security by reducing dependency on traditional credentials.
How I Built It I built this project using Python, leveraging the qrcode library to generate QR codes and SQLite to store user credentials. The process includes:
User Registration: The user enters a username, and a unique QR code is generated. Login Authentication: The system verifies the scanned QR code against stored user data. Challenges Faced One of the main challenges was ensuring secure and efficient authentication while keeping the system simple. I also worked on optimizing QR code storage and retrieval to make the login process smooth and reliable.
