To secure access to your Azure Functions' endpoints to only allowed users, you can use authentication and/or authorization.
Authentication is the process of verifying who you are. Authorization is the process of verifying what you have access to. Authentication and authorization can be used in combination, or separately.
Out-of-the-box, Azure supports both authentication and authorization for HTTP-triggered functions. Additional or alternative authentication and authorization procedures can be implemented in the function's code.
An HTTP-triggered function can be deployed in one of the following modes:
- Anonymous: No authentication or authorization is required to access the function endpoint.
- API key authorization ...
