Abstract

Hundreds of systems at PT. XYZ cause problems in managing credentials, as each user is required to remember multiple credentials. This study developed a QR Code-based Single Sign-On (SSO) system to simplify the login process using the Waterfall model Software Development Life Cycle (SDLC) approach. The login process is completed by scanning a QR Code that represents the user's authentication token, and the login status is synchronized in real-time using WebSocket. The scope of this study is limited to the development of a login page prototype and testing login time and QR scanning time, compared with other methods. This study does not include penetration testing or cryptography. The results from black-box testing show that all features function properly, and User Acceptance Testing (UAT) achieved an average score of 90.4%. Therefore, this QR Code-based SSO login system has proven to be effective, secure, and suitable for use as a modern authentication solution.
