User Names, Passwords and Groups
You may want to change your system access passwords frequently, in order to maintain
optimum security on your network. The recommended passwords are a minimum of 6 and no
more than 12 characters in length, are not found in a dictionary, and contain both letters and

and lowercase letters to provide more possible passwords.
