| Parameter | Description | Value |
|---|---|---|
| number | Specifies the maximum number of historical passwords recorded for each user. If the value is set to 0, the device will not check whether a changed password is the same as any historical password. |

Usage Scenario
To improve password security, it is not recommended that you use a previously used password. You can set the maximum number of historical passwords recorded for each user. When a user changes the password, the device compares the new password against the historical passwords stored on the device. If the new password is the same as a stored password, the device displays an error message to prompt the user that password change fails.
Precautions
When the number of recorded historical passwords reaches the maximum value, the later password will overwrite the earliest password on the device.
