Multi-Factor Authentication (MFA) is quite simple, and organizations are focusing more than ever on creating a smooth user experience. In fact, you probably already use it in some form. For example, you’ve used MFA if you’ve:
- swiped your bank card at the ATM and then entered your PIN (personal ID number).
- logged into a website that sent a numeric code to your phone, which you then entered to gain access to your account.
MFA, sometimes referred to as two-factor authentication or 2FA, is a security enhancement that allows you to present two pieces of evidence – your credentials – when logging in to an account. Your credentials fall into any of these three categories: something you know (like a password or PIN), something you have (like a smart card), or something you are (like your fingerprint). Your credentials must come from two different categories to enhance security – so entering two different passwords would not be considered multi-factor.
