Duo Two-Factor Authentication
If you are a supplier requesting assistance with a supplier portal password reset or multifactor authentication, please contact suppliercare@georgetown.edu.
Two-factor authentication has been added to Georgetown University’s NetID sign-in process.
Note: All students, faculty, staff, and associates are required to enroll in Duo two-factor authentication to University systems.
After you sign in with your NetID and password, you approve access using your mobile device. Click here for details on how to sign up for Duo. (Note: If you replace your mobile phone and Duo was registered on that phone, you’ll need to reactivate Duo on your new phone (new window).)
There are multiple ways to authenticate using Duo—you do not have to use a smart phone!

Step-By-Step Instructions
- Enroll in Duo.
- Fully log out of your account.
- Log in to your Georgetown Google Apps account with your NetID and password. Then follow the steps for confirmation/installation.
Duo Authentication Options
If you are using a smartphone:
- Receive a push notification – when you log in to Duo the Duo application installed on your smartphone or tablet, Duo sends you a push notification with which you can approve the authentication.
- Dynamic passcode – the Duo application on your device will provide you with a dynamically generated passcode that you can use if your device does not have an internet connection.
- Text message – Duo will send you a passcode via SMS that you can enter to gain access.
If you are using a feature (flip) phone:
- Text message – Duo will send you a passcode via SMS that you can enter to gain access.
If you are away from your desk or phone:
- You may contact the UIS Service Center and request a custom bypass code.
- You may enter a bypass code comprising the last nine digits of the CARD number printed on the back of your GOCard. (Note: This method is to be used for GU services [e.g., GMS, Google Apps, GU360, Lynda.com] that use the standard GU login screen.)
- You may enter a bypass code that includes your NetID password, a comma, and the last nine digits of the CARD number printed on the back of your GOCard. (Note: This method is to be used for GU services [e.g., MyAccess, GU Room/Space Reservation System] that do not use the standard GU login screen.)
