Multifactor authentication includes something you know and something you what?

Multifactor authentication (MFA) enhances security by requiring two or more verification factors to gain access to a resource. The factors can be categorized into three types: something you know (like a password or PIN), something you possess (such as a security token, smart card, or mobile device), and something you are (biometric verification, like a fingerprint or facial recognition).

In the context of the question, "something you possess" is the appropriate term that pairs with "something you know" to create a robust authentication method. This combination ensures that access is granted only to individuals who can provide both knowledge (something they know) and a physical item (something they possess), significantly reducing the likelihood of unauthorized access compared to using only one of these factors.

The other terms do not fit into the established framework of MFA. Sharing, remembering, or learning do not contribute directly to the authentication factors used to verify identity in this context. Thus, "something you possess" is the correct response as it encapsulates a key component of multifactor authentication.
