The support ticket system is the only method over which we will accept FTP login information. Any other method is equally "insecure", and we do not take information over the phone due to recordkeeping problems.
If you are honestly concerned that the quality of the apparent security on the connection is an issue, then I remind you that all passwords you send over the network, including with your FTP and email clients, are not over secure links either...
I will inquire about adding an SSL option to the support ticket system.
