User tdrss gives us some practical advice on creating users for FreeBSD and avoiding potential mishaps related to using sudo root. Check out their short guide below which includes using command adduser and setting up sudo. One might utilize this to have separate users for different applications to specify permissions and prevent accidental overwrites.

While most system administrators and power users will roll their eyes at this Instructable, I present it simply to present another way of administering your FreeBSD system. Any novice sysadmin (if they are worth their salt) has done something stupid while logged into the “superuser” root account. I am not discouraging the use of root (when applicable), but allowing you a thin safety-net between any mistakes you might make.
