Duo is Ithaca College's multi-factor authentication (MFA) tool. It requires an extra authentication step, most commonly done by approving a prompt on your smart phone, when logging into many IC systems (Office 365 email, Homer/Banner, IC HR Cloud, etc.). This extra step dramatically improves account security.
