Person or entities authenticated

HIPAA person or entity authentication is the technical process of verifying that an individual or system requesting access to ePHI is exactly who they claim to be, typically through credentials or tokens.

HIPAA 164.312(d) requires organizations to implement formal procedures to verify the identity of any person or entity before granting them access to electronic protected health information.

While HIPAA does not explicitly mention MFA by name, it requires robust authentication. Given modern threat landscapes, regulators strongly encourage MFA as a reasonable and appropriate measure.

Users are typically verified using a combination of something they know (passwords), something they have (security tokens or smartphones), or something they are (biometrics).

Acceptable methods include strong passwords, PINs, smart cards, cryptographic keys, and biometric identifiers, ideally deployed together in a multi-factor authentication strategy.

Authentication verifies the identity of the user (who they are), whereas access control determines what that authenticated user is permitted to do or view within the system (what they can do).

Auditors expect to see a formal authentication policy, proof of unique user IDs, evidence of MFA configuration, and logs capturing all authentication events.

Yes, using shared or generic accounts violates HIPAA requirements because it eliminates the organization's ability to uniquely identify and authenticate the specific person accessing ePHI.

Authentication procedures should be reviewed at least annually, or whenever there are significant changes to the system environment or emerging security threats.

The policy should define password complexity rules, MFA requirements, protocols for authenticating non-human entities (like APIs), and procedures for handling lost credentials.

Authentication controls often fail audits because evidence is scattered across IAM tools, cloud consoles, VPN settings, and policy documents. WatchDog Security's Compliance Center can help teams map authentication evidence to HIPAA 164.312(d), track missing artifacts, and maintain review-ready records for MFA configuration, authentication policies, and access logs.

Person or entity authentication depends on knowing which users, service accounts, API keys, devices, and applications can access ePHI. WatchDog Security's Asset Inventory can help maintain an inventory of systems and identities, making it easier to identify shared accounts, unmanaged service accounts, and authentication gaps.
