This reaffirms what I've been writing here for many years when I publish the advice of security experts. Except in cases in which a weak algorithm is involved that allows passwords of any type to be extracted, strong password algorithms must be coupled with longer passwords that contain a mix of letters, numbers, and, where possible, punctuation.
With Wi-Fi, a 12-character mixed password is probably uncrackable even by government's, while a 20-character passphrase would survive the heat death of the universe.
