@leetaur, I have added our tutorials to the Community Wiki and linked them back to these corresponding forum discussions. Feel free to make any adjustments or corrections in the Wiki that you see fit. (If you don’t have editing privileges yet, you can request them easily from the Wiki page.)
As others are continually offering various suggestions for remote file transfer and/or different ways of enhancing security, I have labeled your Key-based Authentication method as “Option 1” under the Enhancing Security topic. Those other members are invited to add further security options and/or other file transfer methods to the Wiki. (Please keep the instructions simple.)
