Probably not but hey I like doing it.
Just an FYI Auth and Photos use the same server program. I think you can already self host Auth just point the app at your Photos server.
rm -rf my server and lose my 2FA seeds. That’s also why I don’t selfhost bitwarden, even though Vaultwarden is pretty great, and even offers Bitwarden Premium features for free (and I love it cause it’s written in Rust lol)
