How do I set up a new phone with Duo?

I got a new mobile phone to replace one I was using for Duo. How do I set it up to use Duo?

If your new mobile phone has the same number as your previous mobile phone and you were using the Duo Mobile app, follow the steps below to set up your new phone with Duo. 

If your new mobile phone does not use the same number as your previous mobile phone or you were not using Duo Mobile, follow the steps in the related article Add a Device for Multi-Factor Authentication.
