FTP User Authentication

FTP users can authenticate themselves when connecting to the FTP site or to use anonymous access (if allowed by the FTP site). When authenticated using a user name and password, the connection is encrypted. Anonymous users authenticate using anonymous as the user name and a valid email address as the password.
