    UNC computer scientists have published a great paper on why this is so. UNC IT? Forces password change every three months. ¯\_(ツ)_/¯https://twitter.com/perrymetzger/status/834042558342897664 …

    Frequent forced password rotation is a security worst practice. It usually indicates an organization runs on cargo cult security.

        UCL had the same, great human factors of CS researchers but only recently changed. But I heard they still store pws in cleartext.

        The org may fully recognize stupidity of policy, but have little choice. PCI DSS req 8.2.4 says 90 day lifetime, max on PWs , eg.

        I still argue against pw change rules everywhere. I lose the battle to those teams each time.

        passwords that must be changed often are more likely to be written down or stored insecurely. Pass length > youth.

        @SteveBellovin no one listens to wolly headed academics. Especially when they know the subject.
