You seem to be labouring under some pretty egregious misconceptions. I am not signing into something from my phone. The flow is: i try to log into gmail/google docs/whatever on my laptop's browser. Google sends my phone, tablet, any other mobile device I own a notification. if someone taps that notification, the laptop's browser is logged in, with no 2fa. There's no such thing as a phone-wide google account on iPhones. There are google made apps, which completely fuck the security for your google account.
