To define password complexity rules:
STEP 1 Click Security > Password Strength.
STEP 2 Enter the following aging parameters for passwords:
• Password Aging—If selected, the user is prompted to change the password when the
Password Aging Time expires.
• Password Aging Time—Enter the number of days that can elapse before the user is
prompted to change the password.
NOTE Password aging also applies to zero-length passwords (no password).
STEP 3 Select Password Complexity Settings to enable complexity rules for passwords.
If password complexity is enabled, new passwords must conform to the following default
settings:
• Have a minimum length of eight characters.
• Contain characters from at least three character classes (uppercase letters, lowercase
letters, numbers, and special characters available on a standard keyboard).
• Are different from the current password.
• Contain no character that is repeated more than three times consecutively.
• Do not repeat or reverse the users name or any variant reached by changing the case of
the characters.
• Do not repeat or reverse the manufacturers name or any variant reached by changing the
case of the characters.
STEP 4 If the Password Complexity Settings are enabled, the following parameters may be
configured:
• Minimal Password Length—Enter the minimal number of characters required for
passwords.
NOTE A zero-length password (no password) is allowed, and can still have password
aging assigned to it.
• Allowed Character Repetition—Enter the number of times that a character can be
repeated.
• Minimal Number of Character Classes—Enter the number of character classes which
must be present in a password. Character classes are lower case (1), upper case (2),
digits (3), and symbols or special characters (4).
