Duo: Enrollment Guide

Duo is a security authentication tool that adds an additional layer of protection to online accounts. This document provides instructions for enrolling your device in Duo via MyNetID.


Duo is a tool used to improve access security by using two-factor authentication (2FA), also called multi-factor authentication (MFA). Individuals are required to verify their identity by sharing something they know (i.e. userid and password) along with something they have (i.e. a smartphone app). This type of authentication protects Rice systems against cyber attacks.

Rice has several systems that require Duo authentication. Duo's enrollment process makes it easy to register your phone and install the Duo Mobile application on your smartphone or tablet. If you have multiple devices, a smartphone, and a tablet, we recommend that you register both as a hedge against the loss of one device. If, for example, your smartphone is lost, stolen, or damaged, you could use your tablet with DUO, until your smartphone is replaced or repaired. 

Duo prompts you to enroll when you enable Duo Two-Factor Authentication within MyNetID (Online Account Management System).

Supported Browsers: Chrome, Firefox, Safari, Internet Explorer 11, Microsoft Edge, and Opera.

Step 1: Login to the Online Account Management System with your NetID credentials. Select the Sign in button.

Step 2: Select Two-Factor Authentication under Account Maintenance menu or the lock icon on the main screen.

Welcome window that pops up after logging in.


Step 3: Select Enable Two-Factor Authentication.

Step 4: Click Start setup to begin enrolling your device.

Protect your Rice account: Two-factor authentication enhances the security of your account by using a secondary device to verify your identity.

Step 5: Select the type of device you'd like to enroll in and click Continue. We recommend using a smartphone for the best experience, but you can also enroll in a landline telephone, a universal two-factor authentication (U2F) token (currently only works on Chrome browsers), or iOS/Android tablets.

What type of device are you adding? Buttons for device choices.

Step 6: Select your country from the drop-down list and type your phone number. Use the number of your smartphone, landline, or cell phone that you'll have with you when you're logging in to a Duo-protected service. You can enter an extension if you chose Landline in the previous step.

Double-check that you entered it correctly, check the box, and click Continue.

Text entry box for your phone number.

If you're enrolling a tablet you will not be prompted to enter a phone number.

Step 7: Choose your device's operating system and click Continue.

If you do not have a compatible smartphone device or decide not to install the Duo Mobile app: choose Other > Continue > Continue to Login > Enter a passcode. Click Text me new code at the bottom of the window. Enter in the passcode you received from Duo via text message and select Log In. Skip to Step 11.

Select button to indicate type of phone.

Step 8: Install Duo Mobile

Duo Mobile is an app that runs on your smartphone and helps you authenticate quickly and easily. Without it, you'll still be able to log in using a phone call or text message, but for the best experience, we highly recommend you use Duo Mobile. Since Duo Mobile works in any country, it doesn't require a cell service and is more reliable than SMS/Voice, making it the best option for authenticating your device. 

Follow the platform-specific instructions on the screen to install Duo Mobile. After installing Duo Mobile, return to the enrollment window and click I have Duo Mobile installed.

Step 9: Activate Duo Mobile:

Activating the app links it to your account so you can use it for authentication. This will require access to your camera. The application will request access to the camera, which you can temporarily allow. This can be disabled after enrollment.

On your smartphone: activate Duo Mobile by scanning the barcode with the app's built-in barcode scanner. Follow the platform specific instructions for your device:

After you scan the barcode successfully, select Continue.

Step 10: Configure Device Options (optional):

You can use Device Options to give your phone a more descriptive name or select Add another device to start the enrollment process again and add a second phone or another authenticator.

If this is the device you'll use most often with Duo then you may want to enable automatic push requests by going to the When I log in: option and changing the setting from Ask me to choose an authentication method to Automatically send this device a Duo Push or Automatically call this device and click Save. With one of the automatic options enabled, Duo automatically sends an authentication request via push notification to the Duo Mobile app on your smartphone or a phone call to your device (depending on your selection).

Select Continue to login to proceed to the authentication prompt.
