Reboot into single user mode, which will probably let you in as root
without a password:
Ctrl-Alt-F1 to switch out of X windows, if necessary
Ctrl-Alt-Del to reboot
when you get the 10 second countdown, hit space then
Hit return when prompted about the shell. Once you're in run these
fsck -p clean up filesystems in case of unclean shutdown
mount -a mount all filesystems and switch root fs to read/write
You can now either edit /etc/master.passwd using vipw or set a new
password with the passwd(1) command.
If you've set things up so that you need a password to get into single
user mode, then you're going to have to boot from the installation
media to do that. But that's an e-mail for another day.
