    In Ubuntu the root account has no password but is locked by default, so that you can not log in as root using a password. If you paste your public key ( ~/.ssh/id_rsa.pub ) into root's authorized_keys file ( /root/.ssh/authorized_keys ) then you can log in via 'ssh' as root without needing a password.

  2. Yes you can set the root without password to SSH login without password, but it's highly not recommended, user other user then use su to become root.
