This is naive question, but I think a valid one, and I'd love to know what you think, is using a domain name to sign in, just moving the issue of losing an account to the domain provider? So instead of Google, your host controls your sign-in instead?

It is, but you're much less likely to find your account suspended by your domain name provider. People lose Google accounts and Amazon accounts and all kinds of other accounts because there's so much going on with them and something somewhere triggers an automated ban (for Google, we've seen issues with people and their YouTube, or their Play Store apps, or in this case, their Gmail).

But you're far less likely to ever have any issues with your domain name provider, because you literally only have your domain with them, and don't interact with them outside of that.

I would say if you want to be extra safe, your domain provider would NOT be your hosting provider. Because you can lose your hosting, too, and we've seen stories like that here a few times.
