Removing Devices

If you no longer have a device that you enrolled or no longer want to use it to authenticate, follow these steps to remove devices.

1. Go to Onyen Services and click “2-Step Verification for Duo”.
2. Click LOGIN button

3. On Single Sign-On, sign in with your Onyen or Guest ID
4. Current Duo devices are displayed

 

5. Under the question Would you like to make any changes?, click YES.

 

6. Click Manage My Duo Devices.

 

7. On the Single Sign-On, Sign in with your Onyen or Guest ID for a 2nd time.
8. You will be prompted to authenticate with Duo. For example, send a Duo push to your mobile phone.
9. Once the Duo Push is acknowledged on your device you can proceed!
10. The Duo Central interface displays the devices that you have registered.

11. In this example we will remove the Security Key device. Click the Edit link then select Delete.

 

12. Confirm you want to delete the device in the displayed popup. The device will be removed and is no longer available to use, and is not display in Duo Central.

 

Now you can log out and close the browser window.

 

 

 

Reactivating Devices

If you need to activate a new device with the same phone number, follow these instructions:

1. Go to Onyen Services and click “2-Step Verification for Duo”.
2. Click LOGIN button

3. On Single Sign-On, sign in with your Onyen or Guest ID
4. Current Duo devices are displayed

 

5. Under the question Would you like to make any changes?, click YES.

 

6. Click Manage My Duo Devices.

 

7. On the Single Sign-On, Sign in with your Onyen or Guest ID for a 2nd time.
8. Since this process is used when you want to replace a currently registered device with a new device(presumably on the same phone number), sending a Duo push to the currently registered device may not be the best Duo authentication option.  Instead chose the option to send a text passcode to the phone number (or a phone call if applicable)

9. Click the Send a Passcode button

10. Enter the Passcode then click Verify

 

11. Your currently registered devices in Duo Central is displayed

 

12. Under the phone you want to update, click I Have a New Phone

 

13. Click the Get Started button

 

14. Download the Duo mobile app to your new device, if you haven’t already

 

15. Open the app and click the +Add button

 

16. Click the Use QR Code button

 

17. Scan the QR code displayed by the Duo Central app

Your device should be reactivated.

 

Reporting Lost Devices

If you registered more than one device, you can still use the alternate device to authenticate.

If your device was the only one registered, you will need to call the Service Desk at 962-HELP for assistance.

In the future we recommend you set up an alternative device/option. Please see Adding Devices instructions.

 

Verifying Methods

Providing your Onyen and password is step one. Step two is confirming your log in attempt with a second device. Duo provides several ways to confirm it’s really you. Depending on the version of the Duo prompt you see you’ll do one of the following:

• An automatic request to authenticate using your last used authentication method. To switch methods, click Other Options to see a list of the authentication methods you have set up for all devices. (Duo Universal Prompt)

 

• Authentication options for your default device. If you want to use a different device, select the device you want to use from the Device drop-down menu. Then select the method you want to use for that specific device. (Duo Prompt)

Duo Push 

• Click Duo Push.
• An alert will display on your smartphone or tablet.Open the Duo Mobile app and tap the Approve button to authenticate.

Phone call to your landline

• Click Phone Call. You will receive a telephone call from Duo on the telephone number listed first in your Duo profile.
• Answer the telephone and, when prompted, press any key to authenticate.

SMS (Text)

• Click Text message passcode.You will receive a single-use passcode.
