| Reuse limit | Prevent users from re-using the same password. This is the number of old passwords that are checked for duplicates when a user chooses a new password.

| Requirements Expression | Regular expression that describes the password pattern. This is not editable. |
| Requirements Description | Description of the password requirements. This is displayed to users when they set their password. You can choose a custom message if you prefer. |
