Why each option
Multifactor authentication (MFA) requires combining at least two distinct authentication factors from different categories.
Password (something you know) and PIN (something you know) are both knowledge factors, meaning they are two instances of the same authentication factor type.
Password (something you know) and swipe (typically a pattern or gesture, which is also a form of something you know) are both knowledge factors.
Fingerprint (something you are - biometric) and password (something you know - knowledge factor) represent two distinct categories of authentication factors. This combination effectively satisfies the requirements for multifactor authentication on a mobile device.
Swipe (something you know) and PIN (something you know) are both knowledge factors, not distinct authentication factor types for MFA.
