You’ve heard of two-factor authentication (2FA) and its many benefits, but what about multi-factor authentication (MFA)? MFA can go beyond a simple text or authentication app, and might even happen without you knowing it.
Two-factor authentication is a subset of multi-factor authentication. So the core definition of both is essentially the same. MFA simply means that a resource (such as your computer or online account) is secured by more than one type of credential.
The reasoning behind MFA is that there’s an exponential reduction in the odds of someone compromising all of the authentication factors you need, especially if they’re very different in nature.
