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.
