# ``twisted`.`web`.`_auth`.`wrapper``

module documentation
(source)

A guard implementation which supports HTTP header-based authentication schemes.

If no Authorization header is supplied, an anonymous login will be attempted by using a `Anonymous` credentials object. If such a header is supplied and does not contain allowed credentials, or if anonymous login is denied, a 401 will be sent in the response along with WWW-Authenticate headers for each of the allowed authentication schemes.
