Am I to understand that for now I won't be prompted for passwords from those three servers? I did successfully ssh into one of the servers, but I don't want to restart the machine to check if it persists after a reboot. Does it? Also, for backup purposes, if I save /home/user/.ssh/id_rsa.pub and /home/user/.ssh/id_rsa will I be able to put them back into those places and login without a password?</blockquote><div> You won't be prompted for a password unless you protected the keys with one, in which case it acts much the same as sudo. After some expiry period, you'd have to give it again. </div></div>Again, if your key isn't protected itself by a password, then it will persist across reboots/sessions. If you protected the key, the next session will prompt for the password. Yes. You can back up the keys for later use.
