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

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.
