Better question
I had generated a key with ssh password for user root, the others users are
accessing the ssh by user and unix password, but how can i do for user root
only authenticate with the key, not with user and unix password too.
Regards,

as root:
ssh-keygen -t dsa
then copy the resulting key (/root/.ssh/id_dsa.pub) to the destination
machine
as
/root/.ssh/authorised_keys
if you want to set no passphrase you may do so, but I _strongly_ recommend
you
do not. This is host-based authentication - anyone who can get access to
your
system as root can ssh without a password to any destination machine with
this key on it - lose your laptop, give up all your security.
Alternatively, set passphrases and use ssh-agent and ssh-add to manage your
keys - one password per session, keys held in memory.
incidentally, you can do this as normal users too - just create the key as
the
user you wish to ssh as...
