If you did not create any users when you installed the system
      and are thus logged in as root, you should probably create a
      user now with
#adduser
The first time you use adduser, it might ask for some
      defaults to save.  You might want to make the default shell
      csh(1) instead of sh(1), if it suggests
      sh as the default.  Otherwise just press
      enter to accept each default.  These defaults are saved in
      /etc/adduser.conf, an editable file.
Suppose you create a user jack with
      full name Jack Benimble.  Give jack a
      password if security (even kids around who might pound on the
      keyboard) is an issue.  When it asks you if you want to invite
      jack into other groups, type wheel
Login group is ``jack''. Invite jack into other groups: wheelThis will make it possible to log in as
      jack and use the su(1)
      command to become root.  Then you will not get scolded any more for
      logging in as root.
You can quit adduser any time by typing
      Ctrl+C,
      and at the end you will have a chance to approve your new user or
      simply type n for no.  You might want to create
      a second new user so that when you edit jack's login
      files, you will have a hot spare in case something goes
      wrong.
Once you have done this, use exit to get
      back to a login prompt and log in as jack.
      In general, it is a good idea to do as much work as possible as
      an ordinary user who does not have the power—and
      risk—of root.
If you already created a user and you want the user to be
      able to su to root, you can log in as root
      and edit the file /etc/group, adding jack
      to the first line (the group wheel).  But
      first you need to practice vi(1), the text editor—or
      use the simpler text editor, ee(1), installed on recent
      versions of FreeBSD.
To delete a user, use the rmuser
      command.
