I am using 2 factor authentication through google authenticator and forgot to keep backup for one of the websites (cex.io). When I changed to new phone, I uninstalled Google authenticator from the old one. And now I am locked out of my account. I still have access to the phone and I have reinstalled google authenticator.
Now in this situation, is there any possible way to recover the keys for two factor that were saved on my phone? Customer support for cex.io is very slow and I am not sure when they are going to disable two factor so that I can setup for my new phone. If it is relevant, I was using Redmi 1s from Xiomi.
