Duo MFA

Multi-factor authentication (MFA) is a security technology that requires multiple methods of authentication. The goal of MFA is to create a layered defense that makes it more difficult for an unauthorized person to access your account. When you use MFA, you log in using your username, password, and a third factor - either a smartphone app (Duo) or a hardware token. Even if your password is compromised your account will remain secure. It is likely that you may already be familiar with MFA for handling personal accounts such as online banking, social media apps, Google, etc. At Caltech, multi-factor authentication is already required for certain groups and applications and new Caltech accounts.
