I have an MVC client app authenticated by IdentityServer4 using Windows external identity (not Azure Ad). It is working fine except that each time I run the app, the IdentityServer4 login page will display and I need to click on the "Windows" button to continue. My guess is, there must be a way that I can bypass these unnecessary steps, taking "Windows" as default, and login "silently". Can that be done? If so, how?
