TwoAuth respects the people behind the screen. It's a 2FA app built on a simple, radical idea: no tracking, no ads, no data collection. Using a 100% client-side architecture and strong end-to-end encryption (AES-GCM), your sensitive data is protected and never leaves your device.
TwoAuth is compliant with the protocol and respects all the principles included in it: protocol-3305
Advanced Security & Privacy
- Strong Master Password: Secure your entire vault with a master password (minimum 30 characters).
- Encrypted Backups: Create fully encrypted backups protected by a unique, separate encryption key.
- Critical Settings Password: Add an optional, second password to protect access to sensitive settings.
- Progressive Lockout: The app automatically locks for increasing durations after multiple failed password attempts.
- Self-Destruct Mechanism: Optionally configure the app to automatically and securely wipe all data after a set number of failed attempts.
- Access Recovery: Regain access to your vault if you lose your master password using either 10 single-use recovery codes or a unique, one-time reset token.
- Auto-Lock & Visual Obfuscation: The app can automatically lock and blur the screen after a period of inactivity.
Effortless Code Management
- Add Codes Easily: Add new 2FA accounts by entering details manually or by scanning a QR code from an image in your gallery.
- Powerful Search: Instantly find any code by searching for its issuer or account name.
- Safe Deletion: Move codes to a Trash area, from where you can restore them or delete them permanently.
Deep Customization
- Theme Gallery & Accent Colors: Personalize the app's appearance with a rich theme gallery and a custom accent color picker.
- Multi-Language Support: The interface is available in over 20 languages to provide a native experience for people worldwide.
