Otto keeps two-factor codes on every screen you own: iPhone, iPad, Mac, and Apple Watch, with desktop widgets and a watch complication. Everything sits behind Face ID, Touch ID, or a passcode. Secrets live in the keychain and never leave it.

The pleasure is the glanceability. A code is never more than one look away, and the countdown ring tells you whether to type now or wait a tick. Widgets only ever see the accounts you opt in — delete a secret and it purges everywhere, instantly.

Built in August 2026 and verified by 141 tests, including the official RFC 4226 and 6238 vectors. In TestFlight now.
