Introduction to Duo

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, 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
  • Having Duo call your mobile or landline phone
  • Entering a code provided by a small device called a "token" (intended for people who do not have a cell phone or do not work from a fixed location with a landline). 

Once you successfully authenticate, Duo can be set to remember you for up to 14 days. For more information on this, see the Duo FAQ

What applications are not compatible with Duo?

The following applications do NOT work with Duo (these applications cannot perform the extra authentication process). We recommend moving all Ithaca College mail, calendar, contacts, reminders and notes to Microsoft Outlook. Please see under Further Reading for instructions on setting up outlook on various platforms.

  • Windows: Thunderbird
  • macOS (before Mojave): Apple Mail, Calendar, Contacts, Reminders, Notes
  • iOS: (if your iOS is lower than iOS 11: Mail, Calendar, Contacts, Reminders, Notes) Gmail

Why are these applications not supported by Duo?

These applications do not support "Modern Authentication," which is required for the extra authentication step to work. More information on modern authentication

How to enroll and set up your device to use Duo

We highly recommend setting up at least two separate multi-factor authentication devices to reduce the chances of losing access to your account if your primary authentication device is forgotten, lost or damaged.

Duo also supports security hardware tokens (see image below) for users who do not have a cell phone or do not work from a fixed location with a landline. 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).
