considerations
A
password
can
be
any
combination
of
up
to
twelve
characters
(a-z
and
0-9)
and
symbols.
For
security
reasons,
it
is
a
good
idea
to
use
a
strong
password
that
cannot
be
easily
compromised.
Passwords
should
adhere
to
the
following
rules:
v
Have
at
least
eight
characters
in
length
v
Contain
at
least
one
alphabetic
character,
one
numeric
character,
and
one
symbol
v
Contain
at
least
one
of
the
following
symbols:
,

until
a
valid
password
is
typed
from
the
keyboard.
Administrator
or
Supervisor
Password
Note:
The
term
Administrator
Password
is
used
in
this
section.
However,
your
Setup
Utility
might
also
refer
to
a
Supervisor
Password.
When
an
Administrator
Password
is
set,
it
deters
unauthorized
persons
from
changing
configuration
settings.
If
you
are
responsible
for
maintaining
the
settings
of
several
computers,
you
might
want
to
set
an
Administrator
Password.
After
you
set
an
Administrator
Password,
a
password
prompt
is
displayed
each
time
you
try
to
access
the
Setup
Utility
program.
If
both
the
user
and
administrator
passwords
are
set,
you
can
type
either
password.
However,
to
change
any
configuration
settings,
you
must
use
your
administrator
password.
Setting,
