I’ve tried it in the past. This was a few years ago, so it’s possible it’s changed since then. But the reason I’m not choosing it for myself today is that it relies on either Sign in with Google (fine) or magic links to verify the user. I really don’t want to manage email delivery for this project, which is admittedly a stubborn personal choice. It just adds a lot of complexity that I don’t care to spend time on for hobby projects.

Nope. Better with your own domain.
