Encrypted local vault
Items live in SQLite on your Mac, encrypted with AES-256-GCM. The key comes from your master password through Argon2 and stays in memory only while the vault is unlocked.
Alpha
Mimatory
An encrypted password manager that lives on your Mac, fills your browser, and syncs through storage you already own.
Alpha release for macOS. The build isn’t signed yet — the first time, right-click Mimatory in Applications and choose Open.
Everything you keep, in one place
Logins, cards, keys and notes, in an app built to Apple’s design guidelines so it feels at home on your Mac.
17 item types
Logins, secure notes, cards, identities, passports, SSH keys, bank accounts, Wi-Fi, servers, databases, API credentials and more — each with the right fields ready.
Vaults, tags and favorites
Keep work and personal apart in separate vaults. Tag items, mark favorites, archive what you don’t need and restore from the Trash.
One-time passwords
Keep 2FA secrets next to the login and copy the current code. Copy a QR code image and paste it to add one.
Watchtower
Finds weak, reused and incomplete logins on your Mac, and checks passwords against Have I Been Pwned without ever sending them.
Touch ID
Unlock with your fingerprint on a Mac with Touch ID, or type your master password.
Import from 1Password
Export a .1pux file from 1Password and open it with File ▸ Import. Vaults, fields, one-time passwords and attachments come along.
Password generator
Random passwords, passphrases or PINs, made right in the password field.
Quick Access
Press ⌘⇧Space anywhere to search your vault and copy a password without opening the main window.
9 languages
English, 简体中文, 日本語, Español, Português, Русский, Deutsch, Français, Bahasa Indonesia
Sign in from your browser
The extension for Chrome, Edge, Brave, Arc and other Chromium browsers talks to the app directly. No pairing code.
One-click sign-in
On a sign-in page, a small bar at the top offers the account you used last. Press Sign In, or pick another account from the list.
Inline menu
Click into a username or password field and choose a login. Mimatory fills it in and leaves the submit button to you.
Passkeys
On sites that support passkeys, Mimatory can create them and sign you in with them. They’re kept in your vault.
Passwords only when you pick
Until you choose an account, the page sees only names. Then Mimatory reads that one login, for that site only.
Sync on your terms
Connect Google Drive or any WebDAV server, such as Nextcloud or Jianguoyun. Sync stays off until you set it up.
End-to-end encrypted
Only ciphertext leaves your Mac. The sync key is protected by your master password.
Automatic
Changes sync a few seconds after you make them, and every 15 minutes while the vault is unlocked.
Merged item by item
Edits made on two devices are merged per item instead of one copy overwriting the other.
Private by design
Mimatory has no account and no server of its own. Your vault is a file on your Mac.
Local first
Everything works offline. The vault lives in ~/Library/Application Support/Mimatory.
The key is never saved
The vault key exists in memory only while the vault is unlocked. No Keychain copy, no plaintext cache.
Your files, your account
The vault file and its folder can be read by your macOS user only.
No back door
If you forget your master password, nobody can open your vault — not even us. Pick one you’ll remember.
Website icons
Icons come from Google’s favicon service and the site itself. You can turn icon downloads off in Settings.

Questions
macOS says Mimatory can’t be opened.
Alpha builds aren’t signed or notarized yet. In Finder, open Applications, right-click Mimatory, choose Open and confirm. You can also allow it in System Settings ▸ Privacy & Security.
How do I install the browser extension?
For now, load it in developer mode: get the browser-extension folder from the GitHub repository, open chrome://extensions, turn on Developer mode and choose Load unpacked. Keep the app running while you use it.
What if I forget my master password?
There’s no reset. The vault is encrypted with a key made from your master password, so without it the data can’t be read.
Can I move over from 1Password?
Yes. Export a .1pux file from 1Password, then choose File ▸ Import ▸ 1Password (.1pux)… in Mimatory.
