After i go through their enchanced ftp login feature, found out that instead of plain login username and password, you can enable advanced ftp login feature that ask extra question when you perform ftp login to ftp server. Basically, there are 2 extra option, what is your name and where are you from, and only allow ftp login from specific IP address. These better enhance the ftp login feature. More details can be found here: http://www.apollohosting.com/support/ftp_security.php

To enable this enhanced ftp security feature, you have to login to apollo hosting plesk control panel and enable it from there.
