Will user or super user be the one who set it up? Do I have to set up the
authorized_keys in all account or just for root?

Im the root, I have all following files in .ssh directory.
 
authorized_keys  hostkeys       id_dsa_1024_a.pub  id_dsa_1024_b.pub
random_seed id_dsa_1024_a  id_dsa_1024_b      known_hosts

but in all user directory, they are only random_seed and hostkeys in .ssh.
