Vault2FA
A private, offline two-factor authenticator for iPhone.
What it is
Vault2FA generates the six-digit codes that sites ask for at sign-in (TOTP and HOTP, the same standards every authenticator uses). It was built to replace Authy with something that keeps your secrets on your phone and nowhere else.
What it does
- Add accounts by scanning a QR code, importing a screenshot, pasting a setup link, or typing the secret in.
- Bulk-import from other authenticators' export codes.
- Search that's always on screen. Favourites pinned at the top. Drag to reorder.
- Code size you can change in one tap — or by pinching the list.
- Face ID to open the app and to reveal a stored secret.
- Encrypted backups you can open without the app — see the format.
What it doesn't do
It doesn't sync, phone home, show ads, or ask you to create an account. There is no server. Secrets live in the iPhone Keychain, marked device-only, so they aren't copied to iCloud or into device backups. If you want a copy somewhere else, you make one deliberately with an encrypted export.
