2FAS Auth for Android is the general Android authenticator client for the 2FAS open-source multi-factor authentication suite, designed to help users protect their online accounts with secure, rotating one-time passwords and optionally manage related vault entries. This client lets users add and view TOTP and HOTP tokens for countless services, restore and backup token sets across devices, and secure the app with passcodes or biometrics. The Android implementation emphasizes straightforward setup and usage, providing an incremental list of codes that update in real time, quick token management, and compatibility with common OTP QR codes. It also supports sync and optional integration with 2FAS browser extensions to autofill or streamline authentication workflows when signing in to services across devices.
