the article seems pretty self explanatory to me? it just tells you how to set up phpMyAdmin's configuration file to change auth_type to cookie based so that you aren't storing usernames/passwords in that file. I don't think the setting up the control user and password is necessary, though. you should just be able to set blowfish_secret and then set auth_type to cookie with the localhost/port set. but, setting up the control user works fine as well. just read through the article if you want. it tells you everything to do.
