About this app

The purpose of this app is to facilitate access to 2FA tokens managed through Bubka's 2FAuth service.

To do this, an Android App has been developed that reads 2FA accounts from a user server and stores them locally, allowing the generation of 2FA codes even when not connected to the server.

Main Features

- Free and open source - Secure - The vault is encrypted (AES-256-GCM), and can be unlocked with: - PIN (stored encrypted for higher security) - Biometrics (Android Keystore) - Multi-account (an indeterminated number of accounts can be added, from one or multiple 2FAuth servers) - Screen capture prevention - Tap to reveal (capable to show current and next TOTP code) - Click to copy to clipboard (app can be configured to auto be minimized after the OTP has been copied) - Alphabetic/last use sorting - Search by name/issuer - Shortcuts to fast access to accounts by first service name letter or by group - Add an account by QR code or by a form (QR code is not shared with other than your server) - Full Groups and icons management - Icons not at your 2FA server are downloaded from other sources (optionally) - Ability to copy server token or account secret code
