How to share my Ring cameras with other family members?

I am brand new to Ring. I am trying to share my camera views with multiple members of the family. HOWEVER, with two factor authorization required for everything, it is impossible to simply share my account. I "invited" family members to join, but those went into a black hole as far as I can tell. I just want to have more than one smart phone able to monitor the cameras without me having to authorize everything all the time. Half the point would be for them to see what's going on in case my phone isn't working. How can I accomplish this?
