Your programmer is correct. He needs not only access to your site content, but also to the database so he can modify some settings without deleting whatever is already in there. There is no other way unfortunately.

I have dealt with many of my clients that had the same doubts. In my case, my long time presense in this forum has made things easier, i understand that you don't want to allow access to a stranger, but unfortunately the only other way to do it, without specific knowledge, would be to uninstall both WP and Soho and then reinstall WP in the main folder. Of course, whatever you have already in there, will be lost.
