Transfer your Google Authenticator codes from your phone to your Mac or PC. TuFac manages your two-factor accounts locally, generates the one-time codes directly on your device and never sends anything to the network.
- Local & encrypted — accounts are stored in an encrypted local file, never in the cloud
- TOTP codes — generates one-time passwords on the device with live countdown and one-click copy
- Groups & accounts — tree-based organization, drag & drop reordering, per-group colors
- Google Authenticator import — imports accounts from
otpauth-migration://QR codes (screenshots or webcam) and migration QR images, multi-batch supported - Encrypted backup — export/import backups protected by a passphrase (PBKDF2-derived key)
- Flexible accounts — SHA1/SHA256/SHA512/MD5, 6 or 8 digits, configurable period (30s default)
- Dark theme — consistent dark UI, native menus and shortcuts
- Menu bar / tray app — runs in the macOS menu bar or Windows system tray; closing the window hides it, quit via the tray icon menu
- Platforms — macOS (Intel & Apple Silicon) and Windows, as standalone binaries
TuFac is released as ready-to-run packages for macOS (Intel & Apple Silicon) and Windows. Get the latest version from the GitHub Releases page:
| Platform | Package |
|---|---|
| Windows (x64) | TuFac-<version>-windows-x64.exe |
| macOS (Intel) | TuFac-<version>-macos-x86_64.zip |

Unzip the archive and drag TuFac.app into your Applications folder.
The first time you open it, right-click the app and choose Open (macOS Gatekeeper).
TuFac runs as a menu bar app — it does not appear in the Dock; open it via the tray icon.
Run the .exe — no installation required.
TuFac starts in your menu bar (macOS) or system tray (Windows). Click the tray icon to open the window; closing the window only hides the app. To quit TuFac completely, choose Quit in the tray icon menu. Under Settings… you can enable Start at login.
Create a group, add an account with its base32 secret, and select it to see the current TOTP code with live countdown. Use Copy Code to copy it to the clipboard.
Import your existing accounts from Google Authenticator via File → Import from QR Codes...,
either from image files (.png, .jpg, .jpeg, .webp, .bmp) or scanned with your webcam.
Step by step guide for moving your existing Google Authenticator accounts into TuFac.
- Open Google Authenticator on your phone.
- Go to Settings → Transfer accounts → Export accounts (in German: Einstellungen → Konten übertragen → Konten exportieren).
- Authenticator shows the export codes as QR codes, one screen at a time. Screenshot every single one — depending on how many accounts you have, this takes several images (e.g. 3).
- Transfer the screenshots to your computer, e.g. via AirDrop or USB cable. Avoid sending them by e-mail or chat — the QR codes contain your secrets and should never leave your devices over a network.
- In TuFac, open File → Import from QR Codes....
- Select all the screenshot files at once. TuFac reads every QR code from every image and automatically stitches split exports back together, regardless of the order.
- TuFac creates a new group "Imported Accounts" containing all found accounts. (Google's HOTP entries are skipped — only TOTP accounts are imported.)
- Reorganize the accounts as you like: right-click the selected accounts and choose Create Group from N Account(s), or create a group via Groups → New Group and drag & drop the accounts into it.
- Optional: color-code your groups — right-click a group → Color → Set Color... to pick a color, or Remove Color to reset it.
