Explanation
Multifactor authentication (MFA) requires combining at least two distinct authentication factors from different categories.
Common mistakes.
- A. Password (something you know) and PIN (something you know) are both knowledge factors, meaning they are two instances of the same authentication factor type.
- B. Password (something you know) and swipe (typically a pattern or gesture, which is also a form of something you know) are both knowledge factors.
- D. Swipe (something you know) and PIN (something you know) are both knowledge factors, not distinct authentication factor types for MFA.
