Yep. I'm selfhosting it now. Works great but selfhosting isn't straightforward yet, still the best Authy/Google/Microsoft Authenticator drop in replacement with sync.
Is self hosting even worth it for auth? I self-host ente Photos myself, because that way I don't need to pay for a subscription, but auth is free anyway, and the backups are entirely e2ee, right?
I know, but I use the cloud hosted ente auth backup method on purpose, because I don't trust myself with selfhosting and I'm too scared to accidentally 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)
I'm too lazy... Yeah I am pretty nerdy, but I still don't want to spend that much time caring about my selfhosting setup and building a homelab. But I'm glad it works for you, and I'm glad ente created their authenticator in the first place. I would have never expected it from them, since they only used to make ente photos, but there we go, they casually just created the best FOSS auth app.
