Shared User without shared phone

I have set up a ring doorbell camera and another ring camera to view my back yard. I have registered my wife as a shared user, and that works fine for the app. However, when she tries to access the cameras on ring.com from her PC, it asks her to login. She has our account username and password, but ring sends a two step verification to my phone (not hers). Is there any way to allow us to be able to do the verification on different phones? Or is there a batter way to share our account?
