Site Locker - Lock Any Website with PIN

About

Site Locker is a simple, focused Chrome extension that lets you lock any website behind a PIN. Whether you want to password protect a site on a shared computer, block distracting websites while you work, or keep sensitive pages like email or banking private from anyone who picks up your browser, Site Locker blocks the page from loading until the correct PIN is entered.

WHY PEOPLE USE SITE LOCKER
• Password protect any website social media, email, banking, work tools, or anything else
• Block websites you don't want to open accidentally  a lightweight way to stay focused
• Keep a shared or borrowed device private without logging out of every account
• Prevent anyone else who uses your computer from opening specific sites

HOW IT WORKS
1. Set a Master PIN to open the Site Locker settings, and a Site PIN that unlocks the websites you protect.
2. Add any website to your vault lock an entire domain, or just a single page or path.
3. From then on, opening that site or even switching back to an already-open tab — asks for your Site PIN first. No PIN, no access.

KEY FEATURES
• Lock any website: full domain or a specific page/path
• Escalating lockout protection: repeated wrong PIN attempts trigger longer cooldowns, making brute-force guessing pointless
• One-tap Master Switch to pause all locks instantly, and resume just as fast
• Dark and light themes that stay consistent across every screen
• Clean, fast popup UI with no clutter

BUILT FOR PRIVACY
Your Master PIN and Site PIN are never stored in plain text each is hashed with 100,000 iterations before it's saved. Your PINs and your list of locked websites live only in your browser's local storage; we don't operate a server for that data, so there's nothing to leak. Full details are in our Privacy Policy.

FREE AND PRO
The free plan locks 1 website at no cost no account, no sign-up required. Site Locker Pro removes that limit for unlimited locked sites, with flexible billing: a low-cost daily trial, monthly, 6-month, yearly, or a one-time lifetime purchase. Cancel a subscription anytime, instantly, from inside the extension.

Site Locker works on any regular website (http/https) in Chrome and other Chromium-based browsers. Lock the sites that matter to you and take back control of your browsing privacy.
