ASP.Net Development Server prompting for password over VPN

So I solved this problem where a WebForms app prompts me for a password when I VPN into my work computer…

This prompt doesn’t appear normally, and it sucks because you can’t Google an answer for this one

  • asp.net “sign in” disable prompt localhost
  • asp.net disable password prompt vpn
  • asp.net asking for password vpn
You didn’t even know Google had a captcha on their searches, did you? You can trigger one by searching for “asp.net” + anything multiple times.

Google’s no help on this, so let’s post the solution:
Uncheck the “NTLM Authentication” option and the password prompt goes away!

See that NTLM Authentication option? Turn that shit off if you’re working over VPN!
