Last updated: 2026-01-29 18:04:30
After the custom password strength feature is enabled, you can modify the feature parameters in the current cluster and sync them to other clusters under your account. This document describes how to modify such parameters and configure parameter sync.

Prerequisites

You have enabled the custom password strength feature as instructed in Enabling/Disabling Custom Password Strength Feature.

Modifying Custom Password Strength Parameters

Note:
The password check strength levels are divided into MEDIUM and STRONG, with the Prohibited Word Dictionary parameter only appearing when the strength is set to STRONG.
1. Log in to the TDSQL-C for MySQL console.
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 click Strength Settings on the right.


4. In the pop-up window, click Next to enter the Parameter Settings page.
5. Within the parameter modification interface, establish a new parameter configuration, then click OK.


Setting Parameter Sync

Note:
If you are logging into the console using a sub-account, ensure that this sub-account is authorized to use the parameter synchronization function for custom password strength. For detailed authorization function names and operations, please refer to Granting Sub-User Feature Permissions.
After enabling the custom password strength feature in a cluster, you can use the parameter sync feature to sync the configured custom password strength parameters, including Non-Compliant Dictionary, to other clusters in the same region under the current Tencent Cloud account. If this feature is disabled in a target cluster, it will be enabled to sync the parameters.
1. Log in to the TDSQL-C for MySQL console.
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 click Strength Settings on the right.


4. On the parameter modification page, click Parameter Sync.


5. On the Parameter Sync page, select or deselect one or multiple clusters and click OK.
