8.3.5 Initial and reset passwords unique and changed
Where passwords or passphrases serve as authentication factors under Requirement 8.3.1, they must be set and reset for each user so that they are: given a unique value when first issued and whenever reset; and forced to be changed immediately after first use. Customized approach objective: nobody unauthorized can make use of a starting or reset password or passphrase issued to a user.

Version 4.0.1 is the active version; 4.0 has been retired. Appendix A1 applies only to multi-tenant service providers, A2 only to card-present POS POI terminals that still use SSL or early TLS, and A3 only when a payment brand or acquirer requires it. Which requirements apply to you follows your validation type.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
