You can specify rules that determine the character composition of newly created passwords. Be sure to consider the maximum password length when determining values for character requirements. If the total number of letters and numbers exceeds the maximum password length, all passwords are rejected. For example, if Letters and Digits are both set to six, all passwords contain at least 12 characters (6 letters and 6 digits). In this example, if a maximum password length is eight characters, all passwords are rejected.
Password composition settings include:
Specifies a minimum length for user passwords.
Specifies the maximum length for user passwords.
Determines the maximum number of identical characters that can appear consecutively in a password.
For example, if this value is set to 3, then “aaaa” cannot appear anywhere in the password. However, “aaa” is acceptable within a password. Set this value to ensure that users cannot enter passwords of a single character.
Specifies whether to allow upper case alphabetic characters and, if so, the minimum number a password must contain.
Specifies whether to allow lower case alphabetic characters and, if so, the minimum number a password must contain.
Specifies whether to allow letters and if so, the minimum number a password must contain.
Note: The Letters check box is automatically selected when you allow upper or lower case letters.
Specifies whether to allow numbers and, if so, the minimum number a password must contain.
Specifies whether to allow letters and digits, and if so, the minimum number a password must contain. If this setting is set in conjunction with Digits, characters can satisfy both requirements. For example, if this setting and Digits are set to 4, the password “1234” is a valid password.
Note: The Letters and Digits check box is automatically selected when you allow upper or lower case letters, or numbers.
Specifies whether to allow punctuation marks, and if so, the minimum number a password can contain. Punctuation marks can be periods, commas, exclamation marks, slashes, dashes, and hyphens.
Specifies whether to allow non-printable characters, and if so, the minimum number a password can contain. These characters cannot be displayed on a computer screen.
Note: Certain browsers do not support non-printable characters.
Specifies whether to allow non-alphanumeric characters such as punctuation marks and other symbols (“@”, “$”, and “*”) and if so, the minimum number a password can contain. Non-printable characters are also included. A non-alphanumeric character also satisfies Punctuation and Non-printable character requirements.
