Unfortunately our shared/cloud hosting packages do not come with remote MySQL access, remote access is blocked in firewall level. MySQL database service is provided with our shared/cloud hosting packages as a free addon to be used with the hosted website/script. Therefore, there should not be any requirement of accessing it remotely. Providing remote access can result in service misuses because users can use this free addon as a replacement for high end remote database hosting needs. If you have a database hosting requirement, we suggest to go for a VPS or a dedicated server.
If the requirement is to manage the databases or execute SQL queries, you can simply use phpMyAdmin provided within your cPanel. phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc) can be performed via the user interface, while you still have the ability to directly execute any SQL statement.
