An authenticator built for iPhone login moments
Authenticator gives iPhone users a dedicated place for 2FA login codes. It supports QR setup, QR image import, manual setup keys, quick copy, app authentication, Premium encrypted backup, widgets on iOS 17+, and Apple Watch sync on watchOS 10+.
Login codes without another app account
Authenticator does not require an app account. Add TOTP codes from the services you already use, protect access locally, and keep each service's recovery codes in a separate safe place.
For iPhone and Apple devices
The main app supports iOS 15.0 or later. Widgets are built for iOS 17.0 or later, and the Apple Watch companion is built for watchOS 10.0 or later.
That gives users a small Apple-device ecosystem for codes while keeping the iPhone app as the primary place to add, manage, and protect accounts.
| Surface | Verified support |
|---|---|
| iPhone and iPad | Main Authenticator app, iOS 15.0 or later |
| Widgets | Premium WidgetKit/App Intents widgets, iOS 17.0 or later |
| Apple Watch | Premium WatchConnectivity sync, watchOS 10.0 or later |
| Local unlock | Passcode plus Face ID or Touch ID when supported |
Fast setup paths
When a service shows a TOTP setup QR code, scan it. When you only have a setup key, enter it manually. When the QR is saved as an image, import it from Photos.
Authenticator is useful for people who set up many accounts because it keeps the code entry workflow close to the code list.

Can Authenticator back up my 2FA codes?
Premium can unlock encrypted iCloud backup and restore through Apple iCloud Drive and iCloud Keychain. You should still keep each service's backup codes or recovery methods.
What data does Authenticator collect?
Authenticator can collect product interaction analytics that are not linked to your identity and are not used for tracking. Real TOTP secrets, QR payloads, passcodes, salts, hashes, account labels, and issuer labels stay out of logs, analytics, and crash reports.
