browsers don't display authorization header in devtools


Sometimes we need to troubleshoot NTLM or Kerberos configurations.

But browsers (I tried Edge, Firefox, Chrome) don't show the HTTP Authorization header in F12 devtools anymore. This header was shown some in older versions.

I searched all over the devtools. Is there a hidden setting to display the HTTP Authorization header again? I couldn't find any information about this on the internet.

Edit: in this screenshot you can see that Fiddler displays the "Authorization" header in the request headers. In a freshly installed Chrome the header is not shown. enter image description here


Solution

  • For Firefox just set network.http.sanitize-headers-in-logs to false in about:config.
