TouchLock – Fingerprint Browser Lock

Lock your browser profile with Touch ID, Windows Hello, or a 6-digit PIN.

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) ⚡ KEY FEATURES • Profile-level lock — locks ALL tabs, not just one • Biometric unlock — uses WebAuthn platform authenticators (Touch ID / Windows Hello) • 6-digit PIN — secure fallback, hashed with SHA-256 (never stored in plaintext) • Auto-lock on startup — browser locks every time you open it • Idle auto-lock — automatically locks after inactivity (configurable: 1 min to 1 hour) • Manual lock — one-click lock from the toolbar popup • Tab guard system — prevents bypassing the lock screen via new tabs, tab switching, or chrome:// pages • Content overlay — full-screen overlay on every open page, blocks all clicks and keyboard input • PIN recovery — forgot your PIN?
