By the way, you're completely right about password managers. E2E + 2FA and you're done. I wonder what their solution for "single point of failure" is, because there isn't a single one that's not flawed.
Right until you lose your 2FA token, which in Google's case is your phone. And at this point YOU'RE DONE.
I have everything on my phone, I have 2FA on my phone, so if I lose it AND I can't restore my SIM/phone number - even knowing a prroper password for the account I can't do anything to restore the access.
And I really, really don't want to provide my government/country ID to some American company beforehand.
