# LAPolicy.deviceOwnerAuthenticationWithBiometricsOrCompanion

Device owner will be authenticated by biometry or a companion device e.g. Watch, Mac, etc.

## Declaration

```swift
case deviceOwnerAuthenticationWithBiometricsOrCompanion
```

## Discussion

Discussion Companion or biometric authentication is required. If no nearby paired companion device can be found, it behaves as LAPolicyDeviceOwnerAuthenticationWithBiometrics. Similarly, if biometry is unavailable it behaves as LAPolicyDeviceOwnerAuthenticationWithCompanion.         Depending on the companion type and biometry and companion availability,         either a user is asked to authenticate with biometry and on a companion device in parallel         or the companion authentication takes precedence         and a user is asked to authenticate exclusively on the companion device if available.         Users should follow instructions on the companion device to authenticate.
