@nilesh I would also like it if the Google Maps app would stop attempting to sign me in on mobile.
I'm still using Google Authenticator which means I think I'm stuck with cached Google credentials on my phone, and big G has a way of insinuating itself into fucking everything once you give it a toehold.
@klausfiend @nilesh Do you have a requirement to use a specific authenticator app? If not, you could get an open source one from F-Droid https://search.f-droid.org/?q=authenticator&lang=en
