No they're not - the card is the identity, the PIN is the first factor.

- peteretep 8y agoThis is untrue of cards with chips.
- fabricexpert 8y agoSort of - for chip readers that don't have a magnetic swipe on them, yes. However all cards have enough info in the magnetic strip to validate transactions, so if your card ever goes in card reader with a magnetic swipe reader that is compromised it's not a proper factor.
- close04 8y agoIf the "something you have" part of 2FA can be replicated then it's not 2FA. So you need a "something you know" (password, PIN, etc.) and a "something you have" (a phone app authorization, a card that cannot be replicated, etc.). This excludes anything with a magnetic strip from being any part of the 2FA scheme.
