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 login 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 for new Caltech accounts.
