Install & Set Password
Add Locksy to your browser and create your master password in 30 seconds.
Click & Lock
Click the Locksy icon and hit "Lock Current Tab". Your tab is instantly secured.
Password-Protected
Enter your master password to regain access. Only you can unlock your tabs.
Here's What a Locked Tab Looks Like

Signed mortgage & wire details
IRS Tax Center
Tax refund deposit scheduled
Account Security
New 2FA backup codes generated
Anyone who walks by — or sees your shared screen — can read all of it.
This Tab Is Locked
Enter your master password to unlock it.
Protected by Locksy
The page is hidden and encrypted — only your master password brings it back.
It's not just a cover-up. The tab's contents are locked away until you type your password — and they stay locked even if you close the browser or restart your computer.
Everything You Need.
Nothing You Don't.
Built with security and simplicity in mind. Protect your sensitive tabs without compromising on performance.
Privacy Blur Shield
Automatically masks passwords, credit cards, emails, and OTPs on web pages, plus instantly blurs the page overlay when switching windows or leaving your computer.
Auto-Lock Timer
Automatic protection after inactivity. Set your timeout duration (1-480 min) and let Locksy lock your tabs automatically when you step away. Smart activity detection won't interrupt video playback.
Scheduled Locking
Time-based security on autopilot. Lock tabs during specific hours and days automatically—perfect for work hours or sleep time. Overnight schedule support included.
Keyboard Shortcuts
Lock the current tab (Alt+Shift+9), open the manager (Alt+Shift+0), lock every tab (Alt+Shift+8, 3 free uses then Pro), or hide Locksy with Stealth Mode (Alt+Shift+7). All shortcuts are customizable, and locked tabs show a lock icon plus a live badge counter.
Domain Lock
Lock entire domains with wildcard patterns. Auto-lock new tabs matching locked domains with persistent protection.
Biometric Unlock
Unlock protected tabs with your fingerprint or face — Touch ID, Windows Hello, Face ID, Android biometrics, or a USB security key. Your biometric data never leaves your device.
Right-Click Context Menus
Lock tabs instantly from the right-click menu — no popup needed. Lock this tab, lock a domain, lock all tabs, or toggle stealth. Works on pages, links, images, and selected text.
Stealth Mode
Make Locksy completely invisible. Badge counter vanishes, notifications go silent, and locked tabs show a fake "connection refused" error page. Toggle via popup, Alt+Shift+7, or right-click.
Webcam Intruder Capture
Silently captures a local-only webcam snapshot of snoopers trying to guess your password. Dedicated log page lets you review attempt histories and delete photos safely.
Startup Session Lock
Automatically locks your session tabs when the browser launches, including tabs that restore a moment later. Requires Locksy Pro.
Weekly Privacy Reports
Local metrics dashboard tracking locks history, failed snooper attempts, and active security scores. 100% private and generated completely offline.
Custom Lock Screen Messages
Display personalized notes, reminders, or warning messages directly on the lock screen to deter snoopers.
1-Click Unlock All
Unlock all currently protected tabs simultaneously by entering your master password once. Perfect for quick workflow resumption.
Real-Time Intruder Alerts
Get instant browser notifications and visual warnings on the lock screen when someone attempts to access protected tabs.
Strong Password Encryption
Your master password is protected with heavy-duty hashing (PBKDF2, 600k rounds, SHA-256) — the approach security experts recommend, with an estimated 120 years to crack.
Brute-Force Protection
If someone keeps guessing your password, Locksy automatically slows them down with escalating delays — blocking automated cracking tools.
Incognito Mode Support
Works seamlessly in private browsing windows with same security.
8+ Security Layers
Multiple protection mechanisms prevent bypass attempts.
100% Offline
Everything stored locally on your device. No data sent to servers.
No Account Required
Install and start protecting tabs in 30 seconds.
Lock Entire Domains at Once
Protect all tabs matching a domain pattern with intelligent wildcard support. The most powerful way to safeguard multiple tabs automatically.
Lock Entire Domains
Lock all tabs matching a domain pattern like *.google.com or github.com with one action
Persistent Protection
Domain locks persist across browser restarts and sessions—set it once, protected forever
Auto-Lock New Tabs
New tabs matching locked domain patterns are automatically protected the moment they open
Unlock Preferences
Choose to unlock only the current tab or all tabs for a domain. Locksy remembers your choice
Wildcard Support
Use *.example.com to lock all subdomains or example.com for exact domain matching
Domain Manager
Dedicated interface to view, manage, and configure all your locked domains in one place
Unlock with a Touch.
No Password Typing.
Use your fingerprint, face, or a security key to unlock protected tabs in an instant — no password to type. Your fingerprint and face scan always stay on your own device.
Tab Locked
Use your biometric or master password
No real biometric data used · Simulated demo
Your Biometrics Never Leave Your Device
Your fingerprint or face scan is checked by your own device — never sent to Locksy or anyone else. We literally can't see it.
Built on Trusted Sign-In Technology
Uses the same secure, passwordless sign-in that Google, Apple, and Microsoft rely on. Open standard, no proprietary lock-in.
Can't Be Tricked by Fake Sites
Your unlock is tied to Locksy itself, so it can never be reused or replayed on a copycat or phishing page.
Your Master Password Still Works
Biometrics are just for convenience. Your master password is always there as a backup if your device isn't available.
Works with Your Device's Built-In Security
No special setup needed — Locksy works with the fingerprint reader, face camera, or security key you already have.

Recently Added to Locksy
Locksy keeps getting better. Here are the newest ways it helps keep your tabs private — all included in the free version unless noted as Pro.
Master Recovery Key
Create a 16-character emergency key so you can reset your master password offline if you ever forget it. It's hashed and stored safely on your own device.
Smart Sessions
Decide how long Locksy waits before asking for your password again — from strict (every time) up to 60 minutes — with an extra check before sensitive actions.
Privacy Blur Shield & Manager
Automatically blurs passwords, card numbers and one-time codes, and hides the whole page when you switch windows. Pro adds custom blur strength, per-site rules, and a trusted-sites list.
Weekly Privacy Reports
A private, offline dashboard showing your locks, blocked snooping attempts, and a simple security score. Nothing is ever uploaded.
Startup Lock & Webcam Alerts
Re-locks your tabs when the browser reopens, and can quietly take a webcam photo of anyone who fails your password too many times — saved locally, only for you.
Stealth Mode
Makes Locksy invisible: the badge disappears and locked tabs look like an ordinary “this site can’t be reached” error. Toggle it with Alt+Shift+7 or the right-click menu.
Right-Click Menus & Themes
Lock a tab, a whole site, or every tab straight from the right-click menu — no popup needed. Plus a built-in light/dark theme switch.
Auto-Lock & Scheduled Locking
Locks your tabs automatically after you step away, or on a schedule you set by day and time (even overnight). Smart enough not to interrupt a video you're watching.
