Return to verification by email

Why is it that you have implemented a feature i cannot use as generate a authentication code does not even exist in your app?Please return to verification by email so those of us who are not attached at the hip to our cell phone or don't have option to have it during the day may still check on our homes. It is insane that you can authorize your account without your cell phone so a Ring representative may log in to your account and make any changes you request on your behalf (billing, delete cameras, plan updates, orders, etc); but, that same authentication does not give you access to your own stuff.
