Multi-Factor Authentication

Multi-factor authentication (MFA) is a preventative method that employs answers to a combination of prompts that involve something you know, something you have, and something you are to authenticate access into a system. These prompts can range from “where did you go to high school” to biometric methods like fingerprints that can combine passwords with technology by using text messages or emails as an additional authentication step. At least two of the three must be used to achieve MFA.
