Father of Unix Ken Thompson checkmated: Old eight-char password is finally cracked

This raises the hash rate ... so an 8 character password will be found in under a day regardless of hash used assuming it is a crypt password.

Very useful information, however, given the typical password breech of recent times- a million or so sets credentials, what does this mean?

I suggest that most purposes eg. El Reg login, an 8 character password is sufficient, provided it is based on an uncommon pattern involving mixed alphanumeric and symbol characters. Naturally, as the password breeches have also shown, much depends on how the passwords have been hashed, salted (or not) and stored.
