Zero-Knowledge Password Manager

PasswordNexa™

Every password. Only you hold the keys.

PasswordNexa keeps your logins, cards, notes and keys in vaults that are encrypted on your own device. Share safely with family or colleagues, fill sign-ins in your browser, and see which passwords need attention — without Luton Labs ever being able to read a single one.

🎁 Already subscribe to any Luton Labs application? Your Personal vault is free.

Zero Knowledge Encrypted on your device; we cannot read it
Two Secrets Master password plus a Secret Key
Share Safely Family and team vaults, time-limited shares
Free Personal Vault With any Luton Labs subscription

One Safe Place for Every Sign-In

PasswordNexa replaces spreadsheets, sticky notes and the same password everywhere with vaults only you — and the people you choose — can open.

Which of my passwords have shown up in a data breach?
How do I give the family the Wi-Fi and streaming logins without texting them?
Can I let a contractor use one login for a week, then take it back?
Where are we reusing the same password across sites?
How do we move everything over from 1Password, Bitwarden or LastPass?
If someone leaves, can I see what was shared with them?

Set Up Once. Sign In Everywhere.

1

Create Your Vault

Choose a master password. PasswordNexa adds a Secret Key and gives you an Emergency Kit to print or save — the two together are what unlock your vault.

2

Bring Everything In

Import from 1Password, Bitwarden, LastPass or your browser. A review step lets you add, skip, merge or update each item — and spots duplicates for you.

3

Fill, Save & Share

The browser extension fills sign-ins, generates strong passwords that follow each site's rules, and offers to save or update a login when it changes.

Everything You Expect From a Password Manager

Zero-Knowledge Encryption

Items are encrypted in your browser before they are saved, using keys derived from your master password and Secret Key. Our servers store only ciphertext, and sharing uses hybrid post-quantum key exchange.

Vaults, Items & Tags

Keep logins, payment cards, secure notes, identities and keys in as many private vaults as you like, organised with tags and favourites. One-time codes can live alongside the login they belong to.

Shared Vaults & People

Create shared vaults for a household or a team and choose who can view or edit. Share a single item for 1, 3, 7 or 30 days, until a date, or permanently.

Password Health

See weak, reused and breached passwords in one place. The breach check uses a privacy-preserving lookup, so your password itself never leaves your device.

Browser Extension

For Chrome and Edge: fill sign-ins on the page, save new logins and update changed ones, warn before filling a look-alike site, and stop you typing your master password into a website.

Password Generator

Strong, random passwords by default — and when a site has its own rules, such as a 12-character maximum, the generator follows them rather than producing one the site will reject.

Import, Merge & Export

Import from 1Password, Bitwarden, LastPass, your browser or any CSV, then clean up with bulk actions and duplicate merge. Export to CSV or a password-protected file, confirmed with your authenticator.

Account Protection

An authenticator code at every new session, a list of signed-in devices you can sign out, and Lock everywhere for when a laptop goes missing.

Emergency Kit & Recovery

A printable Emergency Kit with a QR code, an optional recovery code, and the ability to change your master password or replace your Secret Key at any time.

A Plan for Every Household and Team

Every paid plan starts with a free trial. Prices are shown when you choose a plan.
