Which of the following is an example of two-factor authentication?

Explanation:
Two-factor authentication requires two separate proofs of identity from different factor categories. The best example here is using a password (something you know) together with a smart card (something you have) to access an EHR. This combination verifies identity through two distinct factors, making unauthorized access more difficult. Biometric authentication alone counts as one factor (something you are). Enforcing password complexity strengthens the single factor (the password) but doesn’t add a second factor. A physician having broader access relates to authorization, not how identity is verified.
