Remember the Very Bad Idea of
giving away dormant account user names that Yahoo came up with last year?
We didn't like it. Nor did other security-minded people, who pointed out that attackers could request a password reset email from popular websites - say, Google or Facebook - in order to hijack the accounts belonging to the original Yahoo account owner.
It came as no surprise when in short order the new holders of the old accounts reported that they were
still receiving mail meant for the accounts' previous owners.
Now, Facebook says that by working with counterparts at Yahoo, they've together come up with a Very Good Idea to counter that Very Bad One.
