The trend from Google continues to be towards "if you lose your phone with your credentials, you will be unable to log in". And Google refuses to create a scalable system that allows you access to your account by verifying your identity in person.
This is a recipe for disaster. And, possibly, a warning to move off GMail before it gets worse.
People complain about government services, but this is something that government is good at. The DMV serves everybody, regardless of personal views, criminal records, etc. Companies can refuse service to anyone for any reason. What happens when you put all your eggs in Google's basket, and then they decide to close your account with no recourse.
Is it possible to control the credentials in your phone and copy them somewhere else?
An added benefit of Fastmail is somehow its calendar is able to sync between my Outlook work calendar and some shared Google calendars I have, while Google is completely unable to reliably sync a shared Outlook calendar for me.
After over a decade of @gmail being my primary personal email it is pretty painstaking to move all of my logins over, and some services do not allow you to change your email at all so your mileage may vary.
They have some tools to migrate email. I was migrating from an IMAP source, the migration was pretty quick and painless.
