Description
Tokn is a lightweight, privacy-first 2FA / MFA authenticator app for one-time passwords (OTP). Your 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 else's cloud.
Looking for something in the spirit of Aegis or Ente Auth, or a fully offline alternative to Authy or Google Authenticator? Tokn covers the same ground, with local device-to-device sync on top.
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. - Multiple devices? Sync your vault via Wi-Fi or a QR code.
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 Expressive 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 - Audit log. Every vault unlock, account change, and settings tweak gets a timestamped entry you can search and filter. - Recycle bin. Deleted accounts wait 30 days before permanent removal, or skip the wait and delete immediately. Configurable.
