Features

Everything you need from a password manager, nothing you do not.

Built for people who want their passwords close at hand and out of everyone else's.

One-click filling

Your logins for the page you are on, right in the login field and at the top of the popup.

Passwords sites accept

A strong password waits in every sign-up form, using the symbols websites allow.

Saves as you go

New logins and changed passwords are offered for saving, with every detail editable first.

Edit anywhere

Change passwords, websites, folders and favorites from the browser. The app catches up by itself.

Live two-factor codes

Two-factor codes refresh on their own and copy with one click. No second app needed.

Touch ID and your own lock time

Unlock with a touch, and choose how long it stays unlocked: from 15 minutes to a week.

Every detail

Copy, reveal and check your passwords

Each login shows its username, password, a live two-factor code and every website it belongs to.

  • A strength check on every password
  • Password history, so an old password is never lost
  • Cards, notes, identities and documents too

Password generator

A strong password, the moment you need one

Click into a new-password field and YanDunLock has one ready. Copy it, fill it, or adjust it first.

  • 20 characters with capitals, numbers and widely accepted symbols
  • Or easy-to-type word passwords
  • Follows each site's own password rules

Privacy by design

Your vault never leaves your computer.

There is no YanDunLock server to break into, and no account to lose. The extension talks only to the YanDunLock app on the same computer.

Encrypted with two keys

Your master password and a Secret Key kept in your computer's keychain. Both are needed to open the vault.

Websites see only their own login

A page gets a password only for its own website, and only when you choose to fill it.

No tracking, ever

No analytics, no advertising and nothing sold or shared. Your data is yours.
