Basically, when you register your mobile on the Wireless, the next
screen comes back with a random alpha-numeric string (6 digits or so)
that is your combination-userid/password for the external website.
Essentially a random password that you can't change. (It could be a
hash (or part of a hash) of some sort on your MAC)
The benefits are that it's quick, simple and low maintenance.
Password recovery is accomplished by returning to the Makery and
accessing the MMM registration page from your mobile again.
