            Basic/Digest/Custom HTTP Auth.

            ``False``, requests will accept any TLS certificate presented by
            the server, and will ignore hostname mismatches and/or expired
            certificates, which will make your application vulnerable to
            man-in-the-middle (MitM) attacks. Setting verify to ``False``
            may be useful during local development or testing.
