KeyVault

Cloud applications and services use cryptographic keys and secrets to help keep information secure. Azure Key Vault safeguards these keys and secrets. When you use Key Vault, you can encrypt authentication keys, storage account keys, data encryption keys, .pfx files, and passwords by using keys that are protected by hardware security modules.

The entry in KeyVault will be added with the device name as a key and the plain GUID as the secret value. See the following example screenshot:
