It depends on what you are trying to do. If it is a task that you do
often, then it is worth while. But for tasks like this, that you do
infrequently, it is handy to have a key pair with a good pass
phrase. You use ssh-agent and ssh-add to unlock the key before
running the script, and then use ssh-add -d to lock it again when
you are done.
