Open-source 2FA authenticator. Encrypted on-device. No accounts.
About this app
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
SWITCHING FROM ANOTHER 2FA APP
Tokn imports backups from Aegis, 2FAS, Google Authenticator and standard otpauth:// URIs. Bring your existing accounts over in minutes.

Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be me.diamondforge.tokn is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.7.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Tokn - MFA / 2FA authenticator first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Tokn - MFA / 2FA authenticator, and a listing is removed when the evidence for it stops holding up.
