PasswordNexa · Passwords, encrypted on your device · by Luton Labs

Try PasswordNexa — no sign-up

You get your own private vault. You choose its master password, you get a real Emergency Kit with your Secret Key, and a set of sample logins is encrypted on your device and saved. Everything is sealed in your browser exactly as it is for a customer — even in the demo, Luton Labs cannot read what you put in.

Sample data only, deleted after 24 hours. Please do not enter real passwords or personal data. Security emails are shown on screen, never sent.

What to try

  • Create your vault: pick a master password (or use the suggested one) and see your Emergency Kit — the Secret Key is made on your device and never sent to us.
  • Sample logins appear, encrypted in your browser: copy a password without showing it, and watch a live two-step code count down.
  • Password Health: weak and reused sample passwords are flagged, and known-breached ones are found without sending a password anywhere.
  • Password Generator: follow a website's password rules (length, symbols, maximums).
  • Lock and unlock (Ctrl+Shift+L): your master password and Secret Key open the vault again.
  • Tags, Favourites, item history and Recently Deleted: every change keeps its earlier versions.
  • Export a password-protected .pnxx file — the authenticator code it asks for is shown at the top of the page.
  • Security Activity and Devices: every browser is certified by your own key.

Switched off in the demo: sharing with other people, joining a Family and a work account, and connecting the browser extension. To use them, sign up.

How your demo vault is protected

The same as a customer's: Argon2id stretches your master password on your device, your Secret Key adds 128 bits only you hold, and every item is sealed with AES-256-GCM before it leaves the browser. The server stores ciphertext and checks signatures; it cannot open anything.
