Guest and shared users are unsafe with Ring

Shared users are not safe in late night secanrios where they can not control lights.

This has been a issue ALL of rings competition has addressed in some fashion.

Since we can not have more than one owner, and ring states MFA/2FA is a best practice, I guess that means only one family member can real count on ring for their safety.

Your current implementation of ring RBAC (roles and permission) makes your product a bad solution the families where MFA is used per rings suggest and the non-owner comes home alone.
