Creating limited logons for access to a website in IIS 10
What is the recommended way to create a limited login to an admin section for a specific website in Windows 2016 for a public-facing webserver in IIS? I see several options: Basic/Digest/Windows authentication methods. I'd like not to have to add a local account for each client if possible, but will if I need to. Part of their admin functionality is to upload and manage images, if that has any impact.
