Allow Basic authentication This policy setting allows you to manage whether the Windows Remote Management (WinRM) client uses Basic authentication. If you enable this policy setting, the WinRM client will use Basic authentication. If WinRM is configured to use HTTP transport, then the user name and password are sent over the network as clear text. If you disable or do not configure this policy setting, then the WinRM client will not use Basic authentication.
