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 checkbox to enable the Repeating Pattern rule.
Select the Detect character substitution checkbox if Password Policy Enforcer should reject passwords that rely on character substitution to comply with this rule.
Select the Bi-directional analysis checkbox 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 dropdown list to specify the maximum number of consecutive matching characters that Password Policy Enforcer tolerates before rejecting a password. For example, the password "mypwd4mypwd5" contains a five-character repeating pattern (shown in bold type). Password Policy Enforcer rejects this password if the tolerance is four or lower, and accepts it if the tolerance is five or higher.
