There are multiple benefits of using multifactor authentication over two-factor authentication systems. First, the flexibility of MFA allows you to customize your level of authentication in a way that 2FA limits. This flexibility also makes MFA more secure than 2FA, because it can layer levels of security based on device reputation or other risk factors. Static 2FA is limited to the authentication parameters you define up front, and doesn’t change dynamically once you are aware of new information and risks, as is the case in newer MFA solutions.

Hear from Michael Thelander, fraud and authentication expert and author of Multi-factor Authentication for Dummies, about the benefits of multifactor authentication over two-factor authentication.

“What are the benefits of using multifactor authentication over a two-factor authentication system?

One of the obvious ones is having more flexibility over what kind of authentication you can put in front of your consumer. How much friction do we want to present in that process? I can put in front of them a very lightweight, easy authentication process. Or I could have them, if there’s high enough risk in what they’re attempting to do or even risk that we perceive in the session or in the device, I could put all three kinds of authentication in front of them. Ask them to give us a knowledge factor, give us a possession factor, and then even provide a thumbprint. But multifactor authentication is more secure all around, provides more assurance, and it’s more flexible than static, two-factor authentication.”
