Über diese App

Authenticator is a full-featured 2FA authenticator app focused on privacy and usability. It generates one-time passcodes (OTP) to help you enable two-factor authentication (2FA) for your important accounts.
Whether you log in every day, manage lots of accounts, use multiple devices (phone/tablet/watch), or need backup and migration, Authenticator provides a stable, smooth, and reliable experience.

What you can do with Authenticator

- Enable 2FA for email, social, cloud services, games, work accounts, and more
- Generate codes anytime offline—no internet required
- Stay in sync across devices: quickly view codes on your phone, tablet, or watch
- Use cloud sync plus import/export for a safer, easier device switch or reinstall

Feature overview

1. OTP code generation
- Supports TOTP / HOTP for common 2FA scenarios
- Works offline: generate codes without an internet connection
- Stable timing and refresh: clear validity/refresh behavior to reduce mistakes
1. Fast setup and management
- Add accounts by scanning QR codes
- Manual setup: enter secrets and parameters when QR scanning isn’t available
- Smart image recognition: automatically identifies service info/icons for a clearer list
- Better organization for many accounts, so you spend less time searching for codes
1. Cloud sync & backup (End-to-End Encryption, E2EE)
- End-to-end encrypted cloud sync/backup
- Data is encrypted on your device before syncing; only ciphertext is stored in the cloud
- Keep multiple devices consistent and switch devices seamlessly
- You stay in control: choose whether to enable sync/backup and when to sync (depending on in-app settings)
1. Import / Export (flexible migration and backup)
- Encrypted export for local backup or migration
- Import to restore after switching devices or reinstalling
- Great for device upgrades, multi-device use, and periodic backups
1. Privacy protection and access control
- Biometric lock / device credentials to protect your accounts in the app
- Helps reduce the risk of someone viewing your codes if they access your device
1. Multi-device experience (phone / tablet / watch)
- Phone: add, organize, back up, and sync accounts easily
- Tablet: clearer viewing on a larger screen, great for work and many accounts
- Watch: view codes at a glance for faster access (device support required)

Why choose Authenticator

- Complete feature set: TOTP/HOTP, cloud sync, import/export, smart recognition, biometric lock, plus tablet/watch support
- Less hassle: sync + backup for smoother device switching and reinstalls
- More peace of mind: E2EE + biometric lock for privacy and protection

Permissions (for transparency and trust)

- Camera: scan QR codes and perform image recognition
- Network: cloud sync and online backup/restore
- Biometric: unlock the app with fingerprint/face/device credentials

Notes

- We recommend enabling cloud sync or exporting encrypted backups regularly to reduce the risk of losing access if your device is lost or damaged.
- Please keep exported backup files and unlock information safe to prevent unauthorized access.
