Access to your Secure FTP would need to be done through an FTP client application by using the following information to log in:
Note for Luminate Online Clients with a custom data sync: Another FTP server exists for the purpose of housing data sync CSV files. To access this separate FTP server, simply append _ds to the end of your username. You'll use the same password to access this.

Many modern FTP clients will use encryption just because it's available, with no other configuration needed. For others, you will have to enable support for AUTH TLS. Details of doing so should be available to you in the documentation with your software.

Specifically, the option to configure your ftp client for is FTP with TLS/SSL (AUTH TLS explicit) - port 21.

If you are using a command-line based FTP client, it will likely encrypt the control channel by default, but be sure to issue the command PRIVATE ON before transferring files, so that the data connections are also encrypted.

For security reasons Convio does not support OpenSSH's SFTP - despite the name, this is not an FTP-based protocol, it is based on SSH.

Automatable CLI clients known to work include:

Windows - MoveItFreely
Linux/Unix - ftp-ssl ( http://sourceforge.net/projects/ftp-ssl/ ) or preinstalled with Debian apt-get

For Windows computers, there are some free to use programs that will make navigating your FTP easier and more intuitive. Some of these programs are SmartFTP, FileZilla and WS-FTP-Pro.
