To minimize the risk of unauthorized access to the Messaging system, follow these guidelines for system administrator passwords.
Establish a new password as soon as the Messaging system is installed.
Use from 6 to 11 alphanumeric characters. The password must include at least one numeric character and two alphabetic characters.
Never use obvious passwords, such as a telephone extension, room number, employee identification number, social security number, or easily guessed numeric or letter combinations.
Do not post, share, print, or write down passwords.
Do not put the password on a programmable function key.
Change the password at least once per month. You can administer your system to age the password and notify you that a new password is required.
