Hi @HapaHacks ,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to understand more about using authentication methods with Azure Front Door.
For an AFD health probe, please refer : AFD Health probes
AFD health probes do not have any authentication method.
Unfortunately, I am not aware of any work around for request authentication.
However, you can secure your monitoring endPoint by using network rules in your Application.
- Health Probes only originate from a set of IP addresses from Azure.
- They are listed under AzureFrontDoor.Frontend service tag
- Refer : How do I lock down the access to my backend to only Azure Front Door?
The challenge here is that these IPs may change, and you will be required to manually update the IPs from the tag in your application
