Supported Authentication Schemes

Specifies which HTTP authentication schemes are supported. When a server or proxy accepts multiple authentication schemes, the supported authentication scheme with the highest security is selected. You can override the default behavior by disabling specific authentication schemes.

  • Basic—Most insecure method with authentication handled without any encryption.
  • Digest—A challenge-response scheme that is more secure than basic authentication.
  • NTLM—(NT LAN Manager) A more advanced challenge-response scheme that is more secure than digest.
  • Negotiate—The most secure option. We recommend this option if available. Otherwise, we recommend NTLM.
