Re: The world needs to be reformatted.
I recently upgraded to a new ISP (now AT&T) and the modem it uses has a default "alphabet soup" password that is restored on factory reset. It appears to be uniquely assigned, and as it's printed on a sticker on the modem itself, and can ALSO be changed (until the next factory reset), I would think that this might satisfy a reasonable security requirement for NOT using identical default passwords and still provide for recoverability (etc.).
At least, as far as I know, none of the (uniquely) pre-assigned passwords are "admin" "love" "sex" "money" "password" or "god"
(so yeah it is one way to do it)
