Change a MySQL user's password from cPanel:
- Log in to cPanel from your client area and open MySQL Databases.
- Scroll to Current Users, find the user, and click Change Password.
- Enter a new strong password (use the generator), confirm, and save.
Important: after changing it, update the same password everywhere your application stores it, for example WordPress's wp-config.php (DB_PASSWORD) or your app's .env file. If you miss this, the site will show a database connection error. If you cannot recall which file holds the credentials, open a ticket.
