Ring App for Android: No Login Requirement is a security hole?

As a new user of Ring and the Ring App, I may have missed something but... having installed the android app, and set up all my Ring security system easily, including adding my door lock, I wonder why I do not need to log into the app to bring it up on my phone? No password, fingerprint, iris, or face recognition, just click the icon and up it comes. If I open my online banking app, it makes me log in, or provide a fingerprint: same goes for other "sensitive" apps. But not the Ring App. I have enabled two factor security, but that just means when I log into this forum, I have to provide the code that is texted to my phone. I still get to see the Ring security system from my phone without providing any security factors, just a single click and I can unlock my front door, turn off the alarms and anything else I see fit to mess with... So if I lose the phone, I am relying upon the finder not figuring out my phone's 4 digit screenlock, 'cos if they do so they then get to unlock my front door, switch the system off and walk in... Surely not...
