Not sure if I'm missing your intentional irony, but NIST was one of the best places to send folks who think user password rotations are a good idea.

I said "was" because pretty much everyone has now caught up, but NIST updated guidance shortly after big breaches were able to be studied.

> Verifiers SHOULD NOT impose other composition rules (e.g., requiring mixtures of different character types or prohibiting consecutively repeated characters) for memorized secrets. 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
