"My initial position is we should shift our guidance away from the old
complex recommendation to a passphrase recommendation."
- totally agree. This paper http://dl.acm.org/citation.cfm?id=1979321 studies
the effects of different password policies to measure the difference in
resulting password complexity. The only constraint they found that
increased complexity was the length. The rest of password policies had
little effect. "Overall, they found that increasing minimum length was more
effective than applying content constraints"
As far as two-factor auth goes, I love my two-factor auth with google and
facebook but one of those factors is still a password. We'll still need to
provide guidance on how to create them. Would anyone be shocked if in
twenty years we still have passwords?
Also, +1 on having password managers suggested in the guidance.
