Tokn 两步验证 应用 为 Android 描述
Tokn is a small, privacy-first 2FA / MFA authenticator. Your one-time codes stay on your device, encrypted. No accounts, no cloud sync, no analytics, no ads.
A simple, open-source TOTP / HOTP authenticator for people who do not want their second factor in someone elses cloud.
WHY TOKN
- Private by design. No sign-up, no telemetry, and no Google Play Services on your device.
- Encrypted vault. Stored in an SQLCipher database, unlocked with biometrics (fingerprint or face) or a password.
- Works fully offline. Codes are generated locally on your phone.
- Open source. GPL-3.0, source available on GitHub, also published on F-Droid.
FEATURES
- TOTP and HOTP support per RFC 6238 and RFC 4226
- SHA-1, SHA-256 and SHA-512
- Add accounts by scanning a QR code with the camera or from a gallery image
- Manual entry for codes you cannot scan
- Biometric unlock with password fallback
- Encrypted backup and restore for moving to a new phone or keeping a copy
- Device-to-device sync over local Wi-Fi, Wi-Fi Direct or animated QR code. Nothing leaves your network and the handshake is end-to-end encrypted
- Organize accounts with custom groups, multiple groups per account
- Custom icons and importable icon packs (Aegis-compatible)
- Material 3 design with light, dark or system theme and optional Material You colors
- Screenshot protection keeps codes out of the recents preview and blocks screen capture
SWITCHING FROM ANOTHER 2FA APP
Tokn imports backups from Aegis, 2FAS, Google Authenticator and standard otpauth:// URIs. Bring your existing accounts over in minutes.
