Supported authentication schemes must be configured.

This setting specifies which HTTP authentication schemes are supported.

The policy can be configured by using these values: "basic", "digest", "ntlm", and "negotiate". Separate multiple values with commas.

If this policy is not configured, all four schemes are used.

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/HTTP authentication/Supported authentication schemes" must be set to "ntlm,negotiate".

Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge

If the value for "AuthSchemes" is not set to "REG_SZ = ntlm,negotiate", this is a finding.

Set the policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/HTTP authentication/Supported authentication schemes" to "ntlm,negotiate".
