Multifactor authentication must include something you what and something you what?

1. know, share

2. know, have

3. have, access

4. know, remember

The correct answer is: know, have

Multifactor authentication (MFA) is a security mechanism that requires two or more distinct forms of identification to verify a user's identity before granting access to a system. This approach significantly strengthens security by requiring various types of credentials. The correct answer specifies "something you know" and "something you have." This aligns with common MFA practices where "something you know" typically refers to a password or a personal identification number (PIN). On the other hand, "something you have" usually refers to a physical device that generates codes, such as a smartphone, hardware token, or smart card. This combination effectively increases security by ensuring that even if a user's password is compromised, an unauthorized person would still need the second factor to gain access. Other options include combinations like "share" or "remember," which do not accurately represent the dimensions needed for MFA. In a secure MFA setup, sharing any information is not acceptable, nor is the simple act of remembering a secure access mechanism.
