How to use two various authentication in single Azure Function App?

Question

I have two http triggered functions in my Azure Function App project ,need to use Function and Admin level authentication for this.

I Know about below two key's and its uses.

HostKey -- Use for Function App all the functions

Function Key -- Use for specific one function of Function App project

Query :

Host key of all the functions of Azure Function App will be same ?, because every functions has own Function key and Host key settings in portal.

but, we can use common host key for all the functions of azure function app ,then why maintaining host key individually in function integrate settings ?

Answer 1

If you press the Click to show to display the value you will notice that all the host keys values are identical between functions under the same function app. so its just a weird (not even weird) ui decision they had to make
