ssh is used under the covers but since password-less ssh is likely not enabled, your password will be prompted for~/.ssh/authorized_keys but the script also ensures the permissions of ~/.ssh/authorized_keys are 0600 - ssh can be super-picky about that so I think it’s a good precaution, especially if the script creates ~/.ssh/authorized_keys!ssh-keygen to create one. I know the prompts can seem a little confusing - I always just accept all of the defaults!
