My answer to this is to use a custom domain with an email aliasing service.
I’ve gone through about half of the 400 accounts in my password manager and moved them over. I’ll migrate the rest over the next week or so.
So, I’m switching from Gmail to Proton for now, but if Proton starts to get worse or Tuta catches up on functionality or there’s a better provider that emerges or I decide to try to self-host, it’s one easy change at the alias provider to redirect all of my mail to a new email provider.




I switched from Google Authenticator to Ente Auth recently and am very, very happy. It works great.
I haven’t tried their other apps yet, though. I intend to take a look at their images app.
