Vault — 2FA Codes

Add accounts, get secure 2FA codes offline, and keep secrets private on your device.

Vault is a fast, private authenticator that generates two-factor (2FA) verification codes entirely on your device.

Add an account by pasting its setup key or the otpauth setup link, and Vault produces time-based one-time passwords (TOTP, RFC 6238) that refresh every 30 seconds — the same codes your favorite services use for secure sign-in.

• On-device by design — secrets are stored only on this iPhone, never uploaded • No account, no cloud, no tracking • Works fully offline • Code masking — hide codes until you tap • One-tap copy with haptic feedback • Clean, focused interface

Vault keeps your second factor where it belongs: with you. Nothing leaves your phone.
