Duo provides the opportunity to add multiple devices or manage devices that you already have enrolled.

On this page:

Getting to Duo Device Manager

The Duo device manager is the place you go to add, delete, and manage the authentication devices you have connected to Duo.


Go to multifactor.newschool.edu

You can go to multifactor.newschool.edu directly or alternatively, you can choose “Enroll or manage a device” from the multi-factor prompt screen

Select Enroll/Manage My Device(s) on the multi-factor setup page

When prompted, confirm your identity by selecting an authentication method and approving the Duo prompt on a previously enrolled device

If you are adding a new device to replace one that you previously activated for Duo Push, do not select the Duo Push authentication method on this page unless you still have the original device. If you do not have the original device, but have a new device with the same phone number, then you can authenticate with a phone call.

If you don't have any devices you can use to authenticate to device management, please contact IT Central at itcentral@newschool.edu or 646.909.4357


After approving a Duo authentication request, you can see all your registered devices in the device management portal

Add a Device

To add a new method of verifying your identity in Duo once you have gone through the manage device prompt above, click "Add a device" and select one of the verification options.

Duo takes you through the steps of adding the new device, just like first-time enrollment. The difference between adding a new device from device management and during first-time enrollment is that when you have finished enrolling the new device you return to the device management page to view all your registered devices, including the new one, instead of continuing to log into an application.

Rename a Device

Once you have gone through the manage device prompt above, click Edit and then Rename to give a device a new name to help you identify it. This new name shows up in the verification method list and on the authentication page when you log in with Duo to make it easier for you to identify which device you're using.

Remove a Device

Once you have gone through the manage device prompt above, to delete a device, click Edit and then Remove. You'll be able to confirm that you want to remove this device before deleting it. Once deleted, a verification device can't be restored, but if you still have the device available you can add it again. You can't delete your only identity verification device.

Reactivate Duo Mobile for an Existing Device

If you have replaced the phone you activated for Duo Push, or if Duo Push stops working, you can get Duo Push working again without contacting your help desk. 

Go to multifactor.newschool.edu and follow the steps above to be directed to the Duo device manager. If you are using a different device with the same phone number, select the call or text option to authenticate into the Duo device manager.

Once in the Duo device manager, click on “I have a new phone link” on the device that needs to be reactivated.

If you still use the same phone number as you did when you first set up the phone to use Duo Push, then click or tap the Text me a link button. When the text message with the link arrives on your phone, tap it to automatically reactivate Duo Mobile on your phone to use Duo Push again. If you don't have Duo Mobile installed be sure to install it before you try to open the activation link in the text message.

If you are using a different phone number than the one you first set up to use Duo Push then you will need to add a new device and delete the old one.

You can also reactivate Duo Mobile for use with Duo Push on a new phone from the device portal if it uses the same phone number as when you set up the original phone in Duo.


Locate the existing phone in the device management portal and click the I have a new phone link
