In what sense? I’m using Chrome Beta on Android, and I don’t recall being prompted to log in. Perhaps there was such a prompt during initial setup, but it has never tried to log me in quietly since.
On a fresh Android, at first boot, it will ask you if you want to sync stuff. I always choose 'no'.
I then proceed onto the settings app, into 'accounts'. There, I tap 'Google' and lo and behold: App-data, Calendar, Contacts, Google Fit Data and People details are all ticked to sync.
I turn them off.
Then I open the default browser. It logs me into Google, by default. I have to explicitly tell it not to.
Google really really wants users to be logged in. That is my experience anyway.
