`8.3.1` Access authenticated with at least one factor

All user access to system components by users and administrators must be authenticated with at least one of these factors: a knowledge factor (for example a password or passphrase); a possession factor (for example a smart card or token device); or an inherence factor (for example a biometric element). Applicability: not intended for point-of-sale terminal user accounts that are limited to a single card number per transaction. This does not replace MFA requirements; it covers in-scope systems that are not otherwise subject to MFA. A digital certificate counts as something you have when unique to one user. Customized approach objective: no account can be reached unless a user identity is presented together with an authentication factor.

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.

First move

Automate the pull from your Identity provider / directory. Scheduled export of users, roles and MFA state from the directory; access-review completion pulled from the IdP, not a spreadsheet.

Common gaps auditors find

Some devices allow console access without any password
Service consoles accept anonymous or guest logins
Certificates are shared among users so they no longer count as a unique factor
