TOTP Authenticator

TOTP Authenticator is a simple app for generating one-time 2FA codes on your device.

Add accounts by scanning a QR code, or enter an otpauth URI or Base32 secret manually. Then open the app to see current six-digit codes and the remaining time before refresh. The app is designed for everyday use without registration, cloud sync, or unnecessary screens.

Features:

- TOTP codes for compatible two-factor authentication services;

- QR code scanning for otpauth://totp account setup;

- manual account setup with otpauth URI or Base32 secret;

- local encrypted storage through the system keychain;

- search across saved accounts;

- tap to copy the current code;

- light, dark, and system theme modes;

- app version, package id, privacy policy, and store rating links in Settings.

Your TOTP secrets and account list are stored locally on the device. Camera access is used only while scanning a QR code and images are not saved by the app. The app does not require an InetTools account. AppMetrica analytics and Sentry diagnostics send only technical app, device, session, and error data; TOTP secrets and generated codes are not sent.

TOTP Authenticator is a utility for generating codes from secrets you add yourself. Keep backup codes from each service separately before changing or resetting your device.
