phpMyAdmin - user account access...?

I have a website with cPanel. It has one user account attached to it (the primary administrator account). I have a developer working with me who needs access to the database, which is accessed through cPanel, then through phpMyAdmin.

I don’t want to give him the primary account details.

Is there an easy way to allow him full access to the database without giving him my account details? I thought it may be possible to create a separate user account for cPanel, restricted to only phpMyAdmin, but apparently that’s not possible.

I know very little about databases. The extent of my knowledge is pretty much just how to install Wordpress on one… I’m foremost a designer. So I may need to be babied through any sort of solution haha.

Any help is really, really appreciated. Thanks in advance.
