Azure Functions triggers can now rely on Key Vault, allowing you to put more secrets under management. It was common practice to store keys, secrets, or passwords on the app setting in the Function App, or to programmatically retrieve those values from Key Vault from code. Now, use a reference to a Key Vault value from Functions app settings, which will be based on the ID and version of that value. This makes it easier to manage sensitive data, as it’s now centralized on Key Vault, and to build more secure applications using Functions.
