Go to united, login, go to My Mileageplus, scroll down. The Profile section at the bottom has a place to "set password".
I also only have 1 credit card attached to my account, its a $0 gift card and type in my credit card number when I purchase.
Yes, I've gone ahead now and set a password, but form what I see now and what the rep told me, I can still login with my MP# and PIN. Can add travelers and whatnot too.
