Which Multi-Factor Authentication (MFA) method relies on a physical device like a smart card?

The correct choice emphasizes the principle of "Something you have," which directly pertains to physical devices that a user possesses as part of the Multi-Factor Authentication process. This category includes items such as smart cards, security tokens, or mobile devices that generate one-time passwords. These physical devices are crucial for verifying identity because they provide an additional layer of security beyond just a password or biometric factor.

In the context of multi-factor authentication, having a physical token ensures that even if a password is compromised, access to the account or system is still protected since the attacker would also need the physical device. This concept makes it significantly harder for unauthorized users to gain access, reinforcing organizational security protocols.

The other options represent different authentication factors. "Something you know" refers to knowledge-based factors, like passwords or PINs. "Something you are" relates to biometrics, such as fingerprints or facial recognition, which analyze physical characteristics. "Somewhere you are" involves location-based authentication, which determines access based on the user's geographic location. While these methods all play important roles in security, they do not rely on a physical device in the way that "Something you have" does, making the second option the most applicable in this context.
