TouchLock – Fingerprint Browser Lock

About

TouchLock locks your entire browser profile behind biometric authentication or a 6-digit PIN — preventing anyone from accessing your tabs, history, downloads, and bookmarks without your permission.

🔒 WHAT IT DOES

TouchLock adds a full-screen lock screen to your browser. When locked, every tab is covered with an overlay that blocks all interaction. No one can peek at your content, switch tabs to sneak past it, or even access the extensions page to disable it.

👆 HOW YOU UNLOCK

• Touch ID (macOS)
• Windows Hello (Windows)
• 6-digit PIN (always available as fallback)
