Instead using nano when you can't find that line try to grep that string to find out if it's really there (Maybe you can't see it ;) )

grep -n PasswordAuthentication  /etc/ssh/sshd_config

It will give you also the line number in file where it is exactly. If there will be nothing, so just try to put that parameter to that file and restart sshd
