What is Georgetown Duo?

Duo is a tool that provides an extra level of security that protects your Georgetown password against hackers. Duo uses a process called “two-factor authentication” to require an additional step at login that ensures your password is protected against theft.

Georgetown Duo provides secure access to Georgetown computing services such as Georgetown Google Apps, Box, GMS, and Canvas, protecting your password against potential attacks.

How does the Georgetown Duo security service work?

You will enroll in Georgetown Duo, install and set up Duo on your mobile device, and set up your mobile device to work with Georgetown Duo. If you’re new to Georgetown, you’ll perform these steps as part of changing your temporary password.

When you log in to Georgetown computing services, Duo will send an authentication notification to your mobile device, and you’ll be prompted to approve the notification. Once you approve the notification, you’ll be able to access your account.
IMPORTANT: Make sure you have your mobile device with you whenever and wherever you log in so you can approve the Duo authentication notification. 

How will logging in to GU Web sites work using the Georgetown Duo security service?

After you log in to a Georgetown computing service (e.g., Google Apps, Box, GMS, Canvas), Duo will ask you to choose an additional authentication method (e.g., send a notification to your device, require you to enter a passcode) that will require you to take an action on the mobile device you enrolled in Georgetown Duo. Once you do this, you’ll be logged in.

Am I required to sign up for Georgetown Duo? 

All students, faculty, staff, and associates are required to sign up for Duo in order to access University systems.

If you’ve previously registered a second (backup) device for Duo, and you have that device with you, you can have Duo send a push to that device when you log in to a GU site.

Note:  With Duo’s two-factor authentication, your Georgetown password should continue to be protected from hackers, so no one should be able to access any GU Web sites you regularly log in to. However, any data on your device (documents, contacts, email addresses) might be accessible; therefore, the data on your device might not be retrievable.
