Quizplus · Accepted Answer

Two-factor authentication is a security mechanism that requires two forms of identification or authentication for access. In the case of a debit card, the two credentials are the card itself and a PIN, which adds an extra layer of security and reduces the risk of unauthorized access. Segmentation and redundancy are not relevant concepts in the context of debit card security.
