Activating International Number

Adding International Phone Number to Duo

This article assumes you have a device already enrolled with Duo and you have it handy to authenticate with.

If you have previously selected the This is my device option, you must clear cache and cookies, use an Incognito/Private browsing.

Login with your KU Online ID and password to Single Sign-On if prompted
On the Duo screen, click Other Options rather than performing your Duo authentication.
Click Manage devices at the bottom.
Authenticate with Duo using your existing device.
- After successfully authenticating with Duo, you'll be redirected to your Duo devices page
Select Add a device.
Select Phone number.
Select your country's code from the scrollable drop-down on the left, and then enter your phone number in the text field to the right.
After setting your appropriate country code and phone number, click "Continue" to add the number.

How to sign in with alternate number

These instructions will outline how to sign in with alternate phone numbers. When you return from your travels you will need to follow these steps again.

When you get the Duo prompt page you you need to select "Other Options"
Then you can select the number you wish to authenticate with or simply choose the method and correct phone number from the list.

Using Duo Mobile with Multiple KU Accounts

Users with multiple KU accounts, such as an admin account (also called "underscore A," due to the format for the username being j123h456_a), will need to use Duo authentication for both accounts. While you can use the same phone number and devices across multiple accounts, you will need to log in to KU single sign-on (SSO) individually for every account you are required to use Duo with, in order to start the enrollment process for that account, including any admin accounts.The instructions and screenshots below assume that the secondary account is an admin account, but they are applicable to any account that uses SSO and Duo authentication.

Setting Up Your Account

Admin accounts must begin the process by signing in to MyIdentity and then clicking on "View Profile".

Like with your initial enrollment (see "First Time Duo Setup" panel above for details on how to process through enrollment, if needed), you will not be able to set up Duo with your admin account until it has been added to the multifactor authentication group. Once you're active in that group, the Duo enrollment will start automatically once you sign in.

If you are using the same phone number to enroll in Duo with both your admin account and your main KU account, enrollment may deviate after you enter your phone number. Instead of being asked to scan the phone number, you will be prompted to verify your phone number.

Click Call Me or Text Me to get a six-digit verification code. The screenshots below detail using the text message option.
Check your text messages or answer the phone call to get the six-digit code.
Type in the code.
Click Verify.
Select Continue.

This will complete the enrollment process and connect your phone number to your admin account.

Managing Multiple Accounts in Duo Mobile Application

Generally, you shouldn't need to interact with the account via the Duo Mobile application if you're using push notifications; once approved, the login process continues. However, if you want to use a mobile passcode you may open up the account and note that both accounts have the same name: "KU." This may not be the case if you set your accounts up in Duo Mobile after the UI change in October 2021; with that change, users were prompted to set up their accounts with a custom name.

As a solution, you can rename the accounts to distinguish between the two. The process is the same on Android and iOS devices, with minor differences in the UI.

Click the three dots located in the upper right corner of the account card.
Select Rename.
Enter the new name for your Duo account. This name will only impact the device you're on; it doesn't change the account name on other Duo devices you may have connected to your KU account.
Click Save.

Viewing Push Notification Details

To view the details of a push notification to see where it comes from, click the notification as it comes in. You can also view these details by opening the Duo Mobile application — when a request is pending, you'll see the full request automatically, or by clicking "(1) Login request waiting" at the top of the application.

Push details will include:

Whether the push came from SSO (called CAS in the screenshot below) or the KU Anywhere VPN.
The account used to send the push notification.
The IP address and location of the request.
The date and time of the login request.
