Pocket2FA

Secure 2FA code client of 2FAuth server that works offline
New in version 0.9.18
Version 0.9.18

- Group filter no longer resets to "All" after syncing with server
- Updated Flutter SDK to 3.44.4
- Upgraded dependencies: flutter_secure_storage, share_plus, and image_picker_android
- Android build tools updated (Gradle 8.14, AGP 8.11.1)
Pocket2FA is a mobile companion for the 2FAuth self-hosted two-factor authentication web application. It generates TOTP and Steam codes locally on your device while synchronizing with your own 2FAuth server.

Features

  • Generates TOTP and Steam OTP codes locally — secrets never leave your device

  • Encrypted storage using platform security (Android Keystore)

  • Optional biometric authentication (fingerprint / face recognition)

  • Real-time code refresh with countdown timer

  • Privacy mode: hide codes by default, reveal with long-press

  • One-tap copy to clipboard

  • Group organisation for easy browsing

  • Service icon support

  • QR code scanning (camera or gallery image)

  • Multiple 2FAuth server support



Requirements

A self-hosted instance of 2FAuth is required. This app does not work as a standalone 2FA manager — it is a native client that extends 2FAuth.

Disclaimer: Independent companion app. I am not the author of 2FAuth.
