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


8 character passwords are no longer recommended and have not been for a couple years now because of the ease with which they are compromised as the latest demonstraton shows.

Content does not matter, even special characters have negligible benefits in a hash this short these days.

Use pass phrases where your admins allow.

Pass phrases are snippets of something that you can remember that make a sentence or nearly a sentence.

A good one had I not just used it on a public forum would be something like:

Don't panic and remember to bring your towel.

That is 42 characters long and won't be crackable until quantum computers are available over the next decade or so.

It is also very easy to remember and not really all that slow to type.

And it is secure, for now.

Pass phrases people: use them, love them, be secure.
