The option is documented as:

  CURLAUTH_BASIC: HTTP Basic authentication. This is the default choice...

i.e. If you request authentication (by setting a username/password) then Basic
authentication is what's used unless it's changed.

The value CURLOPT_HTTPAUTH determines which authentication method is used (when
authentication is enabled), and that option defaults to Basic.
