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 else's 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
