That's what I call a duh-fault password

from here

There are a lot of things I could say about this monumental cock-up by Apple, but I think the most important thing for people to take away right now is:

Leave no default password unchanged

That goes not just for this particular case but all cases of default passwords. If you find them, change them, because eventually defaults become something that everybody knows, and a password that everybody knows isn't a very good password at all.

(Of course a blank password is even worse)
