8.2.2 Shared and generic IDs only by exception
Group, shared or generic IDs, and any other shared authentication credentials, may be used only where needed as an exception, and must be managed so that: use of the ID is blocked unless an exceptional circumstance calls for it; use lasts only as long as the exceptional circumstance requires; a business justification is documented; management explicitly approves the use; the identity of the individual is verified before the account is made available; and every action taken is attributable to one individual user. The guidance suggests password vaults or controls like sudo, and gives a break-glass emergency account as an example of an exception. Applicability: not intended for point-of-sale terminal user accounts that are limited to a single card number per transaction. Objective under the customized approach: all actions carried out with group, shared or generic IDs can be attributed to an individual person.

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.

Common gaps auditors find
- Root or built-in administrator password known by the whole team and used routinely
- No record of who used a shared account at a given time
- Shared account kept permanently enabled rather than for the duration of the exception
- Justification documented but no explicit management approval
