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.
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.
