Biometric authentication is designed to identify individuals based on their unique biological traits. This method utilizes human characteristics such as fingerprints, facial recognition, iris scans, or voice patterns to verify identity. Because these traits are inherently tied to the individual, biometric systems provide a high level of security, reducing the risk of impersonation or unauthorized access.

In contrast, smart card authentication relies on physical cards embedded with chips for access, while token-based authentication uses physical devices (tokens) or software applications to generate unique codes for logging in. Two-factor authentication involves the combination of two separate methods or factors to verify identity, often combining something the user knows (like a password) with something they have (like a token or a biometric scan).

In this question, the focus on identifying human characteristics directly aligns with biometric authentication, making it the appropriate choice.
