Two keys, not one
Your passphrase plus a key held by your computer. Steal the file or learn the passphrase, and you still cannot get in.
A local-first password manager for Windows
Passwords you keep yourself.
PrathakLocker stores your passwords in one locked file on your own computers. There is no account to hack and no company that can be told to hand it over.

Why PrathakLocker
What makes it different
Built for one job: keeping your passwords on the computers you own.
A decoy for the worst day
A second passphrase opens a believable vault of harmless entries, and quietly tells someone you trust.
Sync you do not have to trust
The server only holds a locked copy it cannot read. Downloading it takes a passkey tap.
Windows app, browser and terminal
The same vault in a desktop window, in your browser on this computer, and from the command line.
Locks itself
After a few idle minutes, on sleep, and the moment you lock Windows.
Copies without showing
The password goes to the clipboard without appearing on screen, and is removed soon after.
The tour
How it works, in eleven steps
Use the arrow keys or the buttons. The same tour is inside the app.
Get it
Run PrathakLocker on Windows
PrathakLocker is not offered as a download yet. For now you build it from the source on your own computer, which takes a few minutes.
Build and install
Windows 10 or 11, and Node.js 24 or newer.
In the project folder, run these three commands:
npm installnpm run buildnode dist/cli/main.js app --install-shortcutThe last line adds PrathakLocker to your Start menu and Desktop. Prefer the browser? vault ui opens the same screens in a tab. Prefer the terminal? vault --help lists everything.
- Get the project and run the three commands.
- Open PrathakLocker from the Start menu or the Desktop.
- Create your vault and print the recovery kit.
PrathakLocker opens in a Microsoft Edge window, so it needs Edge, which is already on Windows 10 and 11.
Why no installer? A program that is not signed makes Windows say “Windows protected your PC”, and a password manager should not teach people to click through warnings. Until PrathakLocker can be signed, building it yourself is the honest way.
Honest limits
What it will not do
Good security tools say where they stop. Here is where PrathakLocker does.
- It cannot protect you from malware already running on your computer.
- If you lose both your passphrase and your recovery kit, nobody can get your data back. That is the point.
- The web app is local to your computer. There is no online vault in a browser, because the key that protects it lives in Windows.
- Passkey sign-in has been tested with a software authenticator, not yet on every kind of hardware key.
