How to secure Jellyfin hosted over the internet? (programming.dev)

I already host multiple services via caddy as my reverse proxy. Jellyfin, I am worried about authentication. How do you secure it?

I use good ol' obscurity. My reverse proxy requires that the correct subdomain is used to access any service that I host and my domain has a wildcard entry. So if you access asdf.example.com you get an error, the same for directly accessing my ip, but going to jellyfin.example.com works. And since i don't post my valid urls anywhere no web-scraper can find them. This filters out 99% of bots and the rest are handled using authelia and crowdsec

That’s not how web scrappers work lol. No such thing as obscurity except for humans

It seems to that it works. I don't get any web-scrapers hitting anything but my main domain. I can't find any of my subdomains on google.

Please tell me how you believe that it works. Maybe i overlooked something...

My understanding is that scrappers check every domain and subdomain. You’re making it harder but not impossible. Everything gets scrapped

It would be better if you also did IP whitelisting, rate limiting to prevent bots, bot detection via cloudflare or something similar, etc.
