If you need to update the password for a database user (for security reasons, or if the password has been compromised), you can do this directly from the Plesk interface.

### Changing a Database User Password

1. Log in to **Plesk**.
2. Go to **Databases**.
3. Click the database name the user is associated with.
4. Go to the **Users** tab.
5. Click the username of the user you want to modify.
6. Enter the new password in the **New password** field.
7. Click **OK** to save.

### Important Notes

- After changing the password, you will need to update it in your application configuration file (e.g., `wp-config.php` for WordPress).
- If your application cannot connect to the database after a password change, verify the configuration file has been updated.

### Troubleshooting

**Application shows "Error establishing a database connection" after password change:**

- Update the database password in your application configuration file.
- Verify the username is correct.
