Strict manual, startup, and idle locker with decoy PIN support and offline recovery. By iCommuneTech.

Chrome Lock Pro | Secure Profile Locker | Enterprise-Grade Chrome Lock Extension by iCommuneTech 🔒 The most complete chrome lock extension for securing your browser profile — PIN protection, auto-lock on idle, decoy PIN, intruder alerts, multi-window session restore, and offline TOTP recovery. 100% free. SHA-256 encrypted. Zero data collected. Ever. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY CHROME LOCK PRO? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Your Chrome profile holds your saved passwords, open tabs, browsing history, and signed-in accounts. Chrome Lock Pro | Secure Profile Locker puts a PIN-protected lock screen between your profile and anyone who tries to access it — whether that's a coworker, a family member, or an intruder. Built on a zero-knowledge privacy architecture with SHA-256 PIN encryption and a Tab Morphing anti-crash engine, it's the best chrome extension for locking your profile: enterprise-grade, offline-first, and built so your credentials never leave your device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CORE FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔐 SHA-256 Encrypted Master PIN Your PIN is never stored in plain text. The moment it's created, it's hashed using the native Web Crypto API (SHA-256) — making it highly resistant to local hard drive scraping. Only mathematical hashes are compared to grant access. 🚀 Lock on Startup Automatically intercepts Chrome the moment it opens. All restoring tabs are safely hidden and access is blocked until your PIN is entered. The recommended mode for shared or office computers. ⏱️ Auto-Lock on Idle (Inactivity Timer) Step away and Chrome locks itself. Choose your idle timeout: 15 Seconds, 30 Seconds, 1 Minute, 5 Minutes, 15 Minutes, or 30 Minutes. Uses Chrome's native system state detection — no battery drain, no performance hit. 🖱️ Three Ways to Lock Instantly → Dashboard: Click the red "Lock Browser Now" button in the popup → Right-Click: Context menu "Lock Profile Now" from any webpage → Keyboard: Ctrl+Shift+L (Windows/Linux) / Cmd+Shift+L (macOS) — fully customizable 🕵️ Decoy (Duress) PIN — Premium Failsafe Under pressure? Configure a secondary Decoy PIN. Entering it unlocks the browser but permanently wipes the hidden session memory — Chrome opens to a blank new tab, showing the intruder nothing while protecting your sensitive workspace. This action is irreversible by design. 🛡️ Intruder Alert & Hard Lockdown Protocol Wrong PIN entered 2 times? Intruder logged + Chrome desktop notification sent. Wrong PIN entered 6 times? Hard lockdown activates: → With Authenticator linked: PIN pad disabled, TOTP verification required → Without Authenticator: Strict 60-second live countdown typing ban 🪟 Multi-Window Session Restore Chrome Lock Pro maps every open tab to its parent window — recording exact dimensions, coordinates, and screen state. Enter your Master PIN and your exact multi-window workspace is rebuilt flawlessly, including tab groupings and active tab states. A Rapid Close Safety Net ensures your session vault is never overwritten if the browser closes mid-unlock. 📊 Analytics Dashboard Track Total Locks, Intruder attempts, and the Last Locked timestamp — localized to your region (DD/MM/YYYY for Indian users). Reset stats anytime with one click. 🔑 Offline TOTP Authenticator Recovery Forget your PIN? Recover it safely using Google Authenticator, Authy, or any TOTP app — 100% offline. Scan the generated QR code, verify with your 6-digit code, and create a new Master PIN instantly. 🎨 Dynamic Lock Screen Customization Solid color, image URL, or local image upload (up to 5MB). The lock screen's glass-morphism tint and text colors automatically adapt to your background's brightness — guaranteeing readability in every scenario. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ZERO-KNOWLEDGE PRIVACY — 100% OFFLINE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Chrome Lock Pro is a true zero-knowledge privacy browser extension: ✅ 100% offline — no servers, no cloud, no external communication ✅ Master PIN & TOTP Secret encrypted via SHA-256 and stored only in chrome.storage.local ✅ No browsing history, analytics, or personal data collected or transmitted ✅ No host permissions for external connections ✅ Tab Morphing engine prevents crashes without ever exposing your tabs ✅ No tracking.

This is intentional — it prevents thieves from bypassing the lock by deleting the extension. ⚠️ The Decoy PIN wipe is permanent and irreversible for the current session. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERFECT FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 👨‍💼 Professionals on shared office computers 👨‍👩‍👧 Families with a shared home PC 🏫 Students in lab or library environments 🔒 Anyone who wants a smart lock screen Chrome extension for privacy and peace of mind ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ QUICK SETUP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1.
