FIS Authenticator is a mobile application designed for Android users, serving as a companion to the FIS Infinity IdP identity management service. This app focuses on enhancing security through second factor authentication for registered users, ensuring that access to sensitive information and accounts is protected with an additional layer of security. The app is free to use, making it accessible for individuals and businesses alike.

The primary feature of FIS Authenticator is its ability to generate time-based one-time passwords (TOTPs) that are required during the login process.
