Repeating Pattern Rule

The Repeating Pattern rule rejects passwords that contain repeating character sequences. Users may use repetition to artificially increase the length of a short password. This should be avoided as it can weaken the password.

Select the Enabled check box to enable the Repeating Pattern rule.
Select the Detect character substitution check box if Password Policy Enforcer should reject passwords that rely on character substitution to comply with this rule.
Select the Bi-directional analysis check box if Password Policy Enforcer should search for patterns with their characters reversed. Enabling bi-directional analysis stops users from circumventing this rule by reversing the order of characters in the repeated pattern. For example, a user may enter "password@drowssap" instead of "password@password".
Choose a value from the Tolerance drop-down list to specify the maximum number of consecutive matching characters that Password Policy Enforcer will tolerate before rejecting a password. For example, the password "mypwd4mypwd5" contains a five- character repeating pattern (shown in bold type). Password Policy Enforcer will reject this password if the tolerance is four (or lower), and accept it if the tolerance is five (or higher).
