Yes. We use the more secure SFTP.
After your service is initially provisioned, you will need to log in to the customer portal and create an administrator on your server. You can do this by navigating to your hosting details page. Additional users with varied access & roles can also be created or deleted from this section.
Please note that if you manually create a user on your server directly through a terminal window, you will be unable to modify this user through our portal.
