Multi-Factor Authentication (MFA) FAQs

If you would like to receive a passcode to access applications requiring multi-factor authentication, DUO will ask you to choose an option for authenticating: “Call Me”, “Enter Passcode”, or “Send Me a Push”. Select “Enter a Passcode” and select “Text Me New Codes”. DUO will send a text containing the passcode to your registered device. Enter the passcode that you received into the application to be allowed access.

If you elect to have a passcode sent to your device, you will only need to use the passcode when you wish to access applications requiring multi-factor authentication. The passcode is only good for a limited time. You do not need to keep it. If you need to access the same application again, you can generate a new passcode.

After you enroll in DUO, you will only need use multi-factor authentication to access applications requiring multi-factor authentication, but you only need to register once in order to take advantage of the protection that DUO provides.
