I'm the IT guy for a new non-profit. We aren't separated yet from the company that created us, but we're in the process of separating. I get to decide all this fun stuff.

I had a very brief talk with the IT team for the larger parent company when I started and explained this stupid password rotation thing, as I came from a security background, they wanted nothing of it. Set in their ways.

For the new non-profit that I'm helping spearhead, I'm not sure I'll get away from the password rotation entirely, but I can certainly set it to something more reasonable, like every 365 days, rather than every 60 days or whatever travesty most are dealing with. I'm pretty pleased about this.

NIST agrees, as if their update a few years ago.

> Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically). However, verifiers SHALL force a change if there is evidence of compromise of the authenticator.

This is a really useful thing to keep in mind because even if you aren't directly bound by a requirement to follow the NIST standards, being able to point your policy people at that is handy if you can shift the conversation to “bring our policy in line with NIST” where there's a question about whether they'll later look bad for _not_ having done so. Typically these conversations are driven by risk aversion and things like federal standards help balance that perspective.

Thanks for the direct link, putting this in my back pocket when the discussion inevitably takes place.

Aside from password rotation being a very questionable practice, it actually can cause productivity loss. In a big organisation like mine it can take up to 48 hours for a password change to synchronise across all the internal services. There's also the issue where some endpoint software still uses the old password behind the scenes and fails to log in too many times - causing your account to be locked. I guess you can see my frustration coming through.

I had the joy of dealing with some endpoint software like this in an organization that had mandated password changes every 30 days. Very predictably, people set recurring "change your password" reminders for the 1st of the month and the organization lost an entire day of productivity each month as they locked themselves out of their accounts en masse. So the beginning of the month was always a panicked, all-hands-on-deck day for the help desk as people were waiting on hold for hours to get their account unlocked.
