-You can expand the capabilities of Excel custom functions by integrating with Azure functions. An Azure function allows you to move your code to the cloud so it is not visible from the browser, and you can choose additional languages to run in besides JavaScript. Also an Azure function can integrate with other Azure services such as message queues and storage. And you can share the function with other clients.

 ### AzureFunctionProject notes
 
-The Azure function is configured to allow anonymous access which means anyone can call the function if they have the URL. This is only for development purposes. In production code, you should configure [authentication and authorization in Azure App Service](https://docs.microsoft.com/azure/app-service/overview-authentication-authorization), to ensure only authorized users and code can call your Azure functions.
