The MySQL access data can be found in the Control Panel under [Webhosting] by selecting the [Databases] option. If a database has already been created, the database name will be displayed, e.g. u12345db7.
If no database is displayed, you will need to create a new database first.
The database name is also the MySQL username.
The password cannot be viewed afterwards. However, you can click on the pencil icon to the right of the database and set a new password in the next step.
You can access your database, for example, via phpMyAdmin by clicking the database icon to the right of your database.
You also have the option to connect to your database externally. For this, you need either the MySQL or PostgreSQL hostname. You can find both pieces of information under [Webhosting] by clicking on [Data sheet].
