AuthBox Vault

Zero-knowledge password and API key vault for developers and AI builders.

Auth Box is a zero-knowledge vault for your passwords, API keys, secure notes, and two-factor codes — all encrypted on your device with keys only you control.

ZERO-KNOWLEDGE SECURITY Your vault is encrypted with AES-256-GCM on your device. We can't see your data — even if we wanted to. Recovery uses a 24-word seed phrase (the same proven model as Bitcoin wallets).

EVERYTHING IN ONE VAULT

• Store unlimited passwords, API keys, and secure notes
• Built-in authenticator: keep your TOTP two-factor codes alongside their logins
• Deterministic password generator — same seed + site = the same strong password, offline
• Watch-only crypto wallet: track BTC and ETH balances by public address

AUTOFILL Fill passwords and one-time codes directly in Safari and apps with the iOS AutoFill Credential Provider — everything stays on device.

WORKS WITHOUT US Your vault works entirely offline and there is no account to create. If Auth Box disappears tomorrow, your 24 words recover everything.
