# deviceVerificationNonce

The UUID for computing the device verification value.

```
var deviceVerificationNonce: UUID { get }
```

## Discussion

Use the lowercased nonce when computing the [`deviceVerification`](/documentation/StoreKit/VerificationResult/deviceVerification-5hvi9) value.

This value is identical to the [`deviceVerificationNonce`](/documentation/StoreKit/Product/SubscriptionInfo/RenewalInfo/deviceVerificationNonce) value in [`Product.SubscriptionInfo.RenewalInfo`](/documentation/StoreKit/Product/SubscriptionInfo/RenewalInfo).
