Duo is Ithaca College's multi-factor authentication (MFA) tool, which requires an extra authentication step (most commonly done by approving a prompt on your smart phone) when logging into certain IC systems such as email. This extra step dramatically decreases the ability for someone to gain unauthorized access to your account.

How does Duo work?
Logging in to your Homerconnect account, Canvas account, Outlook email and other Office 365 applications, such as OneNote and OneDrive for Business, will require your Netpass username and password, as usual, along with a second authentication step using one of these methods:
- Approving a prompt from the Duo Mobile app on your smart phone
- Entering a code provided by the Duo Mobile app
- Entering a code provided by a small device called a "token" (intended for people who do not have a cell phone)
Once you successfully authenticate, Duo can be set to remember you for up to 90 days. For more information on this, see the Duo FAQ

How to enroll and set up your device to use Duo

Note: The phone number of your device facilitates the setup process. If you are traveling abroad with a different number, the "send me a push" and "enter bypass code/passcode" function will still work. It will utilize Wifi connection for this function.
If you are traveling where there is no internet access for your cell phone, the passcode function in the app will also still work. The app has a "cache" of accepted passcodes that will allow you to still use your device.

Duo also supports security hardware tokens (see image below) for users who do not have a cell phone. These devices must be purchased for about $22 from the Ithaca College Bookstore by the user or their department (at the department's discretion). These devices require additional in-person assistance by the Service Desk to set up (Job Hall 104).
