Browser Lock is a security extension designed to protect your browser with password or PIN protection. Its main purpose is to prevent unauthorized access to your browser tabs, history, and settings, ensuring your personal data remains secure on shared computers.

Key features include password and PIN protection that allows you to lock your entire browser or specific tabs in one click. The extension offers auto-lock and timeout functionality that automatically locks the browser after inactivity, making it ideal for shared devices. It includes a kiosk mode for secure single-session browsing on public or workplace computers, and tab lock capability to protect only specific tabs like banking or email.

The extension operates by running lightly in the background and activating only when needed. Once enabled, it behaves like a locked browser until you unlock it with your password or PIN, preventing anyone from opening or using your browser without authorization.

Browser Lock provides privacy and security benefits for users who need to protect their browsing activity from nosy coworkers, roommates, or anyone else who might access shared computers. It's particularly useful for maintaining privacy on shared devices at work, libraries, or home environments.

The product is designed for anyone needing browser privacy protection on shared computers, including users at workplaces, schools, libraries, and homes with shared devices. It's built specifically as a Chrome extension and emphasizes privacy-first principles with no browsing data collection.
