AITS, 2FA, General Information and why you need 2FA

What is two-factor authentication (2FA) and why do I need it?

A great summary about 2FA and its importance can be found here:

Some important points:

Graduate students, staff and faculty are required to use 2FA
Undergraduates are required to use 2FA for System HR (formerly NESSIE) if they have direct deposit setup

What services will be behind 2FA?
There are multiple authentication systems on campus. The main ones which will be covered by 2FA are Shibboleth, Office 365, and some SiteMinder applications. This covers hundreds of applications but some of the most prominent are Compass2g (blackboard), Box,, learn@illinois (Moodle) and Office 365. 
Certain parts of NESSIE and Banner are already behind 2FA.

What if I’m off campus?

The 2FA interface can be accessed via NetID center ( and supports enrollment from off-campus if you have previously specified a secondary email account with the university. Contact or 217-244-7000 for additional help with enrolling from off campus.

What if I’m locked out?

The NetID center ( allows you to set a recovery email address. It is recommend you set this to facilitate recovery. Temporary codes can be sent here in the event your phone is lost or you are otherwise unable to use your normal 2FA device. More information is available at,

What if I don’t have Cellular or WiFi access?

The DUO mobile app (free), available for Apple and Android devices, works without any connectivity. You can replace your SIM card, change providers, turn on airplane mode, or travel internationally and the Duo App works. The common “Push” prompt won’t be available, but the App works by generating a short 6 digit code that you can type into the web application prompt.

What if I don’t have a smart phone? (Information on tokens)

Cell phones, tablets and many devices are supported by the DUO mobile app (android and ios available).  This is the “preferred” method and method that most find the easiest. It works even without wifi or cellular service. Push notifications take mere seconds and integrate with many other devices.  Tokens are available in the WebStore, search “2FA”. Three kinds of tokens are available, a $10 token (displays a code), a $35 token (USB Yubikey) and a $45 token (USB-C Yubikey). The Yubikey is also the accessibility/disability version.

What if I don’t want to buy a token or use one from the WebStore?

Token purchase and management is being handled by each college or department. Please contact your local IT or Business office about providing you a token. The campus does not support tokens purchased from vendors outside of the campus WebStore.
