No authenticator and totally locked out of all Ring accounts

Hi, I have a Ring app and account, so that someone else can share their camera with me. I have no cameras myself. I used an authenticator app for logging in, as well as username+password. Somehow, I no longer have the Ring account on my authenticator, but the login to the Ring app demands the authenticator code. I am totally locked out of the app and web portal. Every piece of advice is around using the control centre, but I cannot login to the control centre, as I have no authenticator code. Is it possible in any way to log into anything (App, or website) without the authenticator. Everything I do seems to want an authenticator code, when I try to log in. PS - I am using the device owners account to submit this message.
