    If you like, you can turn off straight passwords and have both at once or nothing...
    Just enter a password when the ssh-keygen program prompts you for a password. I usually don't, as I feel it's secure enough... and easier not to have to, but you have the option.

    Some handy ssh-keygen options:
    -t rsa1 / rsa / dsa (selects key type, rsa is default, is fine mostly)
    -b xxxx (sets number of bits, 768 (weaker) to 4096 (paranoid), 2048 is default)

    For more, type "ssh tutorial" into Google, or "man ssh" into terminal.
    Then you will find out all sorts of things, eg port forwarding to bypass firewalls

    Also keep your kernel updated as much as you can, the attacker could have used an exploit which attacks the kernel, gains root, and he could've just done an rm -rf /*
