# deviceOwnerAuthenticationWithBiometricsOrWatch

User authentication with either biometry or Apple Watch.

```
static var deviceOwnerAuthenticationWithBiometricsOrWatch: LAPolicy { get }
```

## Discussion

You use the [`deviceOwnerAuthenticationWithBiometricsOrWatch`](/documentation/LocalAuthentication/LAPolicy/deviceOwnerAuthenticationWithBiometricsOrWatch) policy when calling the [`evaluatePolicy(_:localizedReason:reply:)`](/documentation/LocalAuthentication/LAContext/evaluatePolicy(_:localizedReason:reply:)) method to authenticate the user with either Apple Watch or biometrics. The authentication mechanisms run in parallel until one or the other succeeds, or until the user cancels the operation.

If the evaluation method can’t find a nearby, paired Apple Watch running watchOS 6 or later, this policy reverts to the behavior of the [`LAPolicy.deviceOwnerAuthenticationWithBiometrics`](/documentation/LocalAuthentication/LAPolicy/deviceOwnerAuthenticationWithBiometrics) policy. If biometry is unavailable, the policy behaves like the [`deviceOwnerAuthenticationWithWatch`](/documentation/LocalAuthentication/LAPolicy/deviceOwnerAuthenticationWithWatch) policy.

To allow the user to authenticate with either of these options or a password, use the [`LAPolicy.deviceOwnerAuthentication`](/documentation/LocalAuthentication/LAPolicy/deviceOwnerAuthentication) policy instead.
