I’d like to add a login/password form (basic authentication popup in browser is ok don’t need more) in existing asp.net app I didn’t develop but for which I have access to deployment directory.
I’d like to be able to do this without entering their source code only web config or iis config something like htaccess in Apache/PHP/
Does this exist in IIS/ASP.NET ?
Basic authentication could be configured at IIS level:
