Duo: Linking an Existing Device with Duo App

If your authentication method is no longer supported, but you have an existing device in Duo, you can link the Duo App on that device with your account.

If you previously used SMS codes or phone calls to sign in to your Carleton account, and now have to switch to Duo push notifications, you can edit an existing Device and link it to the Duo Mobile app.
