Is this authentication method description correct?

Certificate-based authentication is a valid authentication mechanism for verifying both user and device identities. It relies on Public Key Infrastructure (PKI), in which a trusted Certificate Authority issues a digital certificate containing the subject's public key and identifying information. During authentication, the certificate holder demonstrates possession of the corresponding private key, and the receiving system validates the certificate's trust chain, validity period, revocation status, intended use, and other policy requirements.

This model can authenticate individual users through certificates stored on smart cards, security tokens, or endpoint certificate stores. The same mechanism can authenticate managed computers, servers, and other devices by issuing device-specific certificates. Because the private key does not need to be transmitted to the authenticating service, certificate-based authentication provides stronger resistance to credential theft than reusable passwords when implemented correctly.

The statement therefore accurately describes a recognized authentication method applicable within broader enterprise identity and access-management architectures.
