Frequently Asked Question
 
															Is phishing-resistant authentication alone acceptable as multi-factor authentication for PCI DSS Requirements 8.4.1 and 8.4.3?
No, phishing-resistant authentication cannot be used without an additional authentication factor to meet Requirements 8.4.1 or 8.4.3 because of the increased risk with these types of access.
Use of phishing-resistant authentication is encouraged and recommended; however, to meet Requirements 8.4.1 and 8.4.3 for MFA, phishing-resistant authentication must be used with another factor (for example, a password, PIN, or biometric).
