PanicVault stores everything in a single KeePass .kdbx (v4) file — the open format also used by KeePassXC and Strongbox — rather than locking your passwords into a proprietary cloud. It fills credentials through the system AutoFill provider, stores passkeys alongside passwords, and generates TOTP codes for two-factor logins, all unlockable with Face ID or Touch ID. There’s no account and no PanicVault server; syncing across devices is optional, routed through your own iCloud Drive or Google Drive.
