Multi-factor Authentication

Definition

Requiring proof of two or more pieces of evidence in order to authenticate a user.

How it works

When logging into an account users present two or more credentials that fall into different categories: something you know (password or PIN), something you have (smart card or phone), or something you are (fingerprint).

Considerations

MFA configuration steps may vary across accounts and in some cases left up to users to activate and implement.
