TouchLock – Fingerprint Browser Lock by Mathinraj

TouchLock is a browser security extension that locks your entire browser profile behind biometric authentication (Touch ID / Windows Hello) or a secure PIN.

Features:

• Biometric Unlock – Use Touch ID or Windows Hello as the primary authentication method via WebAuthn
• Flexible PIN (4–10 digits) – Choose your own PIN length with a live strength indicator; encrypted with SHA-256 + random salt
• Profile-Level Lock – Blocks access to all tabs, history, downloads, and settings until authenticated
• Keyboard Shortcut – Instantly lock the browser with Alt+L (fully customizable); auto-synced via browser.commands
• Auto-Lock on Idle – Configurable idle timeout to lock automatically after inactivity (1 min – 1 hour)
• Lock on Startup – Require authentication every time the browser opens
• Tab Guard System – Prevents bypassing via new tabs, tab switching, or about:addons navigation
• PIN Recovery – Reset your PIN using pre-configured security questions (encrypted answers)
• Request a Feature – Built-in feedback form to suggest improvements or report bugs
