Some TWiki scripts (at present these are ViewCgiScript and RdiffCgiScript) can be accessed through two filenames (and hence invoked through two URLs), with or without diff suffix (for example, view and viewauth). .htaccess file instructs ApacheServer to authenticate clients that use the variant of URL with auth suffix, so when a script is invoked through such an URL, it is said to work in AuthenticatedMode. On the contrary, the variant of URL without auth suffix is accessed without authentication, in this case a script works in NonAuthenticatedMode.

Note: the above describes the recommended configuration for TWikiSites that need view access restriction; the TWikiSite administrator can decide to set up TWiki in a different way.
