Two-factor authentication

Two-factor authentication (2FA), powered by DUO, adds an extra layer of security to your University accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from accessing your accounts, even if they know your password.

There is no cost to use 2FA with the Duo mobile app or SMS code, however if you wish to use a third-party dedicated security token such as Yubikey, you or your department will have to make separate arrangements. Please visit Yubico's website for more information on Yubikey.
