How to hide admin account in WPFORO? (for security reasons)

I would like to hide the admin account completely from WPFORO FORUM for security reasons. For example with a regular WordPress blog I would have two separate accounts (one with admin privileges that remains hidden, and another one with only an Editor role to publish all the articles). That way the admin account would be hidden from the public and anyone trying to break in would have to guess both the password AND username.
