FTP servers often permit anonymous logins. This means users log in as the 'anonymous' user, and don't require a password.
In CompleteFTP anonymous logins are disabled by default, but can be enabled via the Settings window, as shown below. The Anonymous Logins section has a checkbox for Anonymous logins enabled. This should be checked if anonymous logins are to be permitted.
To prevent malicious users logging in multiple times anonymously, the maximum number of anonymous logins can also be set. The default is 10, but if anonymous logins are enabled this should be set to a number in keeping with the site requirements.
