You have the option to manage your MySQL databases via phpMyAdmin as well, in order to make various changes to the databases or retrieve their contents.
To access phpMyAdmin, click in the easyname Control Panel on [Webhosting] - [Databases] → [Open phpMyAdmin for this database] to the right of the desired database.
If you have lost the password for your database, you can usually find it in the configuration file of the respective application linked to the database (e.g., "wp-config.php" in WordPress).
