Profile Lock — Password lock for your browser

Lock your Chrome profile with a password. Lock instantly, by shortcut, or after idle. 100% local, no cloud, no tracking.

Profile Lock adds a password lock to your Chrome profile — perfect for shared and family computers. • Set a password on first run, with a one-time recovery code. • Lock instantly from the popup or with Ctrl/⌘ + Shift + L. • Auto-lock after a set number of idle minutes. • When locked, all tabs are hidden behind a lock screen and restored after you unlock. • Bilingual interface: English & Tiếng Việt. • 100% local: no account, no cloud, no analytics, no tracking. Your password is stored only as a PBKDF2 hash on your device. Note: This is a "soft lock" — a strong deterrent, but not OS-level security. A technically skilled person could disable the extension from chrome://extensions. For tamper-proof use on shared machines, deploy via enterprise policy.
