Similar to standard NTLM authentication, NTLM with www-auth authentication is commonly used in corporate and on-premise SharePoint instances. Your username will be formatted as a domain login (e.g. domain\username) when prompted for login credentials.

SPGo will automatically create the correct headers to enable www-auth.

Additional Configuration

To specify NTLM with www-auth authentication, set the authenticationType property to NTLM in your spgo.json file, or by selecting the “NTLM” option when configuring your local environment with the SPGO> Configure Workspace command.
