Authentication Factor

Definitions

1. A category of evidence used to verify identity, such as something you know, have, or are. Multiple authentication factors are combined in MFA to make account compromise harder.

   In plain English: One type of proof used to verify who someone is.

   Example: "A push approval is one authentication factor, but it should be paired with something stronger than a reused password."
