How to disable user password login (that's not root) and another thing

+1 Carlos Henriques · September 13, 2015
I did see the video about how to disable root password, but if we should have another user in the superuser group, and we don't disable his password, isn't disabling root password almost useless? Or is it impossible to someone to see the other user?

How can we connect to a linux server to a different port that ins't 22? I know how to change the port, but not how to connect in linux (only in PuTTY)

Thanks a lot.
