2. Select the region at the top, find the target cluster in the cluster list, and click the cluster ID to enter the cluster management page.
3. On the cluster management page, select Account Management and enable Custom Password Strength on the right.
4. In the pop-up window, click Next to enter the initial settings page.
5. Complete the following settings and click OK.
In the initial settings of the custom password strength feature, two scenarios will be displayed for different password strength levels.
Scenario 1: The password strength level is MEDIUM.
Parameter
Description
Password Strength Level
You can select
MEDIUM
or
STRONG
as the strength level.
MEDIUM: The feature under this setting will check the length, digits, letters, and symbols.
STRONG: The feature under this setting will check the length, digits, letters, symbols, and non-compliant word dictionary.
Min Number of Uppercase and Lowercase Pair
The minimum number of pairs of uppercase and lowercase letters that the password must contain. For example, if this parameter is set to `2`, the password must contain at least two uppercase letters and two lowercase letters. Default value: `1`. Value range: 1–50.
Min Number of Digits
The minimum number of digits that the password must contain. Default value: `1`. Value range: 1–50.
Min Number of Symbols
The minimum number of special symbols that the password must contain. Default value: `1`. Value range: 1–50.
Min Password Length
The minimum length of the password. Default value: `8`. Value range: 8–256. This parameter equals to the number of digits + number of symbols + 2 * number of letters, and it must be greater than or equal to 8 for security of your password. If the final value after the sum of above parameters is greater than 8, it will be used as the minimum of the range.
Scenario 2: The password strength level is **STRONG**.
Parameter

Min Password Length
The minimum length of the password. Default value: `8`. Value range: 8–256. This parameter equals to the number of digits + number of symbols + 2 * number of letters, and it must be greater than or equal to 8 for security of your password. If the final value after the sum of above parameters is greater than 8, it will be used as the minimum of the range.
Non-Compliant Dictionary
If the password strength level is STRONG, this parameter is configurable. You can click Dictionary Settings for configuration. Each non-compliant word can contain 4–100 letters. After configuration, the system will check passwords for non-compliant words during password verification. If any non-compliant word (case-insensitive) is detected, the verification will fail.
2. Select the region at the top, find the target cluster in the cluster list, and click the cluster ID to enter the cluster management page.
