Lock sensitive Mac applications using Touch ID, Apple Watch, or your password the exact moment you step away from your device.
Download for macOS
Built directly on Apple's LocalAuthentication framework. Securely gate individual applications and unlock them instantly using your Mac's Touch ID sensor or by simply wearing your Apple Watch. Absolute security with zero friction.
Advanced background helper architecture. A dedicated process monitors the protection layer status. If a process attempt tries to forcefully kill the lock, the helper instantly deploys and re-locks the screen.
The moment an application is locked, a secure native blur overlay covers the entire window, entirely obscuring sensitive interfaces or personal text data from prying eyes.
Run BioUnlock invisibly in the background. Hide the system menu bar icon entirely to keep your security layer completely hidden, while retaining instant access to your settings via your secure custom hotkey.
Stepping away from your Mac workstation in a rush? Trigger a customizable global hotkey listener sequence to cleanly lock all configured targets simultaneously.
BioUnlock is completely free to use for one application. Upgrading to BioUnlock Pro removes this limit entirely and unlocks advanced security customization. Upgrade once, own it forever.
