PassChain
A fully client-side password manager. No servers, no subscriptions — your vault stays in your own cloud drive, end-to-end encrypted.
Serverless architecture
Your vault lives in a cloud drive folder of your choice. All encryption happens on-device — PassChain runs no sync servers of its own.
Conflict-free multi-device sync
Edit on any device and changes merge automatically on sync — no conflicts, no lost data, even with concurrent edits.
Full-featured password management
Folders, tags, custom fields, a built-in password generator, plus weak / reused / breached password detection.
System-wide AutoFill
Enable it in Settings, and PassChain becomes available as an AutoFill provider across Safari and other apps.
TOTP one-time codes
Add TOTP by scanning a QR code or entering a URI. See the current code at a glance, and use it directly from AutoFill.
Passkeys
Store and use passkeys from your vault, with registration and authentication handled natively.
Security & privacy
End-to-end encryption with Face ID unlock. No background network activity, and your vault is never uploaded anywhere.
