A user then creates a Neopet out of the available 54 and chooses its unique name, its physical characteristics, and its personality and may own up to four per account ( five if the user in question is subscribed to Premium Portal ).

However, in the case of a computer system, a password is usually stored for each user account, thus making all access traceable ( save, of course, in the case of users sharing passwords ).

It can also signify a layman with only user account privileges, as opposed to a power user or administrator, who have knowledge of, and access to, superuser accounts.

However, use of the term continued to spread, partly because in Unix-style computer operating systems, " user " designates all unprivileged accounts, while the superuser, or root, is the special user account used for system administration.
