Problem Statement
Which factor is an example of 'something you have' in multi-factor authentication?
Explanation
Multi-factor authentication (MFA) enhances security by combining two or more independent credentials from different categories — something you know, something you have, and something you are.
‘Something you know’ is a password or PIN. ‘Something you have’ is a physical or digital item like a smart card, phone, or security token. ‘Something you are’ refers to biometrics such as fingerprints or facial recognition.
MFA significantly reduces the risk of unauthorized access, even if one factor, like a password, is compromised.
