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.

Source: PCI DSS v4.0.1, 8.2.2. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open PCI DSS v4.0.1 in the compliance library.

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.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

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.
