What to know
How it works
Stores logins, passkeys, credit cards, secure notes and TOTP codes in an encrypted vault, built on the open KDBX format compatible with KeePass and KeePassXC, with one-tap AutoFill and Face ID across iPhone, iPad, Mac, Windows and Linux.
What's different
Uses the open KDBX format instead of a proprietary vault, so you're not locked into one vendor, with zero-knowledge on-device encryption before sync.
Best for
People wanting a KeePass-compatible password vault across Apple, Windows and Linux devices without vendor lock-in.
