MFA (Multi-Factor Authentication) is a method of verifying a user’s identity by requiring two or more factors or attributes that belong to different categories. The categories are something you know (such as a password or a PIN), something you have (such as a token or a smart card), something you are (such as a fingerprint or an iris scan), something you do (such as a gesture or a voice command), and somewhere you are (such as a location or an IP address). In this case, the user enters a password (something you know) and then receives an authentication code (something you have) to log in to a workstation.

A zero-day vulnerability is a security flaw that is unknown to the vendor and the public, and therefore has no patch or fix available. A zero-day attack is an exploit that takes advantage of a zero-day vulnerability before the vendor or the security community becomes aware of it. A zero-day attack can cause serious damage to a system or network, as there is no defense against it until a patch is released. References:
