In plain words

This is a proof-of-concept project demonstrating QR code-based login authentication. It is intended for developers and technical users interested in alternative authentication methods. The project explores using QR codes as a means to log into systems, offering a different approach to traditional password-based or multi-factor authentication workflows.

  • Scan QR codes to check in guests registered via Google Forms2023 · workspace.google.com · ▲115

    Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption.
