Gated-execute on NIST SP 800-63B password rules, current revision

This is the current revision (800-63B-4), according to the page I opened.

All requirements come from Sec. 3.1.1.2 of NIST SP 800-63B-4 (https://pages.nist.gov/800-63-4/sp800-63b.html). Nothing I found conflicted with the task.

• Minimum length: Passwords used as the only factor must be at least 15 characters. Passwords used only as part of multi-factor authentication may be shorter, but not below 8 characters.
• Maximum length: Verifiers and CSPs SHOULD permit at least 64 characters.
• Composition rules: SHALL NOT be imposed.
• Periodic change: SHALL NOT be required. A change is forced only if there is evidence of compromise.
• Password hints: SHALL NOT be permitted if an unauthenticated claimant can see them.
• Security questions: SHALL NOT prompt for KBA or security questions when a password is chosen.
• Blocklist: Verifiers SHALL compare a new password against a blocklist. The standard sets no number for this.
• Password managers: Verifiers SHALL allow password managers and autofill.
• Salt length: The salt SHALL be at least 32 bits.
• Hashing scheme: Using an approved scheme from the latest revision of SP 800-132 is only a SHOULD. The same sentence also allows "updated NIST guidelines on password hashing schemes". The separate SHALL is that passwords be salted and hashed with a suitable scheme.
