Multifactor authentication requires two or more different forms of verification to authenticate the user. Having multiple factors enhances security by combining something the user knows, has, or is, making it much harder for unauthorized users to gain access. An example of this could be combining a password (something you know) with a fingerprint scan (something you are) or with a physical token (something you have). Single-factor authentication involves only one kind of credential, which is not as secure as multifactor. Personality verification isn't commonly recognized as a standard factor for secure authentication. Continuous authentication could involve multifactor methods but is specifically a process of ongoing authentication rather than being an authentication factor itself.
