When using multi-factor authentication (MFA), a password is considered something you __________.

In the context of multi-factor authentication (MFA), a password is categorized as something you "know." MFA enhances security by requiring two or more verification methods before granting access to an account. The three main factors of authentication are:

1. Something you know – typically a password or PIN.
2. Something you have – like a security token or a mobile device that receives a code.
3. Something you are – which refers to biometric identifiers, such as fingerprints or facial recognition.

Since a password fits squarely in the "something you know" category, it reflects the knowledge-based factor that users must remember and input to verify their identity. This is distinct from the physical and biometric factors utilized in MFA, emphasizing the role of passwords as foundational elements in securing user accounts. Understanding these categories helps reinforce the importance of strong passwords and the layered security approach that MFA employs to protect sensitive data.
