I have a script that goes out to 5 other Rpi3 computers and collects data from them using scp and puts it all out on a flash drive. (Then later it gets picked up from the master Pi by a Windows Task for backup to a hard drive.)
It needs to be put into cron so I don't need to initiate it manually. But it prompts for the password of each remote Pi as it runs.
How do I solve this?
For reference, you can see a description of my entire Rpi3 network in my answer to this question:
