Multi-factor authentication with Duo

What is multi-factor authentication?

Multi-factor authentication (MFA), sometimes referred to as two-factor authentication (2FA), is a method where users obtain access by providing two separate factors to identify themselves. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.
