In Chromium Edge Dev (80.0.345.0) it started (was a few build back actually) getting a modal "Windows Security" dialog when trying to access my authenticated Intranet sites. Followed by the usual "Sign in to access this site" top center dialog.
Using Chrome i just get the "Sign in to access this site" dialog.
So my question is, why does Edge have this extra "Windows Security" dialog, it is quite annoying particularly as it does not prefill any information, like the other dialog does. It also sometimes crashes the browser i have found. So i have to go back to chrome to be able to access some authenticated pages.
