Removal of the toor user
By default, FreeBSD ships with an additional user that has a UID of 0.
This user is known as toor (root backwards), and is intended as a
backup user, so that if you mistakenly broke (for eg) root's shell, you
could log in using this user and fix things. The account is disabled
(passwordless) by default, and hence of no use UNLESS you change it's
password. You may either choose to set a password for it, or remove it.
DALnet suggests you remove this account.
It should be noted that the rmuser(8) command will not allow the
deletion of an account with a UID of 0, so you will need to use
vipw(8) to remove this account.
