Explanation

A callback to a mobile phone is an example of a "something you have" factor in multi-factor authentication. "Something you have" factors require possession of a physical object, such as a phone, token, or smart card, as part of the authentication process. "Something you know" factors involve knowledge-based information, such as a password or PIN, while "somewhere you are" and "something you are" factors are based on physical location or biometric characteristics, respectively. A callback to a mobile phone is not a "something you know" factor, as it does not involve knowledge-based information; it is not a "somewhere you are" factor, as it does not involve location-based authentication. Finally, it is also not a "something you are" factor, as it does not involve biometric authentication
