NIST seems to have it as a guideline for memorised secrets:
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.
I don't want to take away from the initial topic at hand but I'd genuinely be interested to hear what similarities and differences you encounter (as someone who once thought of working in a female dominated workplace but got reality checked quickly out of the idea by bad experiences)
