cyber duck secure transfer?

 Hope this is in the right forum, if it isn't sorry!! Wondering if anyone else gets a message from cyber duck asking before you transfer files to ATV if you want to use a secure transfer? what password do i use? Is it faster? Also can I use an ethernet connection to transfer files from cyber duck? Thanks for your help in advance

You won't need a secure transfer.  This is unnecessary when transferring files on a local network and will result in slower transfer speeds.
