| 1. Before you activate a new phone, you must be at a computer and go to https://duoportal.clarkson.edu. NOTE: You may need your old phone available to get past the DUO push authentication |
|
| 2. Once you are at the Duo My Settings & Devices screen (see image to the right), keep this window |   |
| If you have a university-purchased cellphone, follow the activation instructions that came with your phone. This is done typically by calling the Verizon activation portal (1-877-807-4646) from a separate device. DO NOT CALL FROM EITHER YOUR OLD PHONE OR YOUR NEW PHONE. |   |
| On your new phone, go to the App Store and search for Duo Mobile and then install the app. Open the app and if prompted, be sure to allow the app access to your camera. |
  |
| Once your new phone is active and you have the Duo Mobile app installed, return to your computer with the Duo My Settings & Devices screen open and click on +Add another device. |   |
| Select Mobile Phone - Click Continue |   |
| Enter the cellphone number, even if it is the same as your old cellphone - Click Continue If you do use the same number as your old phone, you will get a message that says "The number already exists, replace it?" See below. Make sure that box is checked before clicking Continue   |
  |
| Assuming that you already installed the Duo Mobile app on your new phone as described above, click "I have Duo Mobile Installed." This will take you to another screen - Activate Duo Mobile for iOS - which contains a QR code. |
|
| With the QR code on your computer screen, pick up the new cellphone, open the Duo Mobile App (if prompted, be sure to allow the app access to your camera) and tap the + button in the upper right. | Hold the phone up pointing at your computer screen to scan the QR code. Once successful, you will notice a checkmark on the computer screen and you can then click Continue. It will ask you to use one of the two verification methods to make sure the new device is working |
|
If your new phone also has a new phone number, you should remove the old device/number from the portal.
- Locate the older device in the section My Settings & Devices - Click Device Options
- Click the red trashcan icon
Click the Remove button to confirm the deletion
