Edit /etc/ttys, and remove the 'secure' token from the terminals
appropriate for your setup. i.e:
console "/usr/libexec/getty Pc" pc3 off secure
Note, once you remove secure, you will not be able to log in as root on
that terminal, so make sure you have a usable account created and listed
in /etc/group under 'wheel' so that you can 'su'.
(Or make sure you have setup sudo or other alternative methods)
Removing secure will cause booting to require a password to get into
single-user mode.
