OTP Authenticator is a two-factor authentication App for Android 14+.
It implements Time-based One-time Passwords (TOTP) like specified in RFC 6238. Simply scan the QR code and login with the generated 6-digit code.
This fork is intended as a lightweight, minimal tool for testing and development workflows. Its primary goal is to keep your test TOTP keys separate from your main authentication setup, so you don’t clutter your primary authenticator app with temporary or experimental codes.
For production use a more robust, feature-rich, and actively maintained TOTP app such as Aegis.
- Free and Open-Source
