Selfhosted

My setup is: Proxmox - restricted LXC running docker which runs jellyfin, tailscale funnel as reverse proxy and certificate provider. So so don't care about jellyfin security, it can get hacked / broken , its an end road. If so i will delete the LXC and bring it up again using backups. Also i dont think someone will risk or use time to hack a jellyfin server. My strategy is, with webservices that don't have critical personal data, i have them isolated in instances. I don't rely on security on anything besides the firewall. And i try not to have services with personal sensitive data, and if i do, on my local lan with the needed protections. If i need access to it outside my local lan, vpn.

For web access, stick it behind a reverse proxy and use something like Authentik/Authelia/SSO provider of your choice to secure it.

For full access including native clients, set up a VPN.

My setup: Locally (all in docker):

• JF for managing and local access
• JF with read only mounted volumes that uses the network of my Wireguard client container
• Wireguard client opening a tunnel to Wireguard server on VPS ** Ping container regularly doing pings to Wireguard Server so the connection stays up (didn't manage it otherwise)

VPS (Oracle Cloud free tier, also everything in docker):

• Caddy as a reverse proxy with https enabled and geolocking (only certain countries are allowed to connect to)
• fail2ban to block IPs that try to bruteforce credentials
• Wireguard server

Usernames are not shown in the frontend and have to be entered. Passwords are generated by a password manager and can't be changed by the user.

So my clients just get the URL of my reverse proxy and can access the read only JF through my Wireguard tunnel. Didn't have to open any ports on my side. If someone is interested I can share the docker compose files later.

~~Jellyfin is secure by default, as long as you have https. Just chose a secure password~~

OpenVPN

CloudFlare tunnel with Zero Trust, plus their bot and abuse blocking. Users can get in with the right oauth, plus only allowed from the countries I know they're in. Then just their username and password on jellyfin.

I use Pangolin (https://github.com/fosrl/pangolin)

You could put authentik in front of it too

Is it just you that uses it, or do friends and family use it too?

The best way to secure it is to use a VPN like Tailscale, which avoids having to expose it to the public internet.

This is what I do for our security cameras. My wife installed Tailscale on her laptop and phone, created an account, and I added her to my Tailnet. I created a home screen icon for the Blue Iris web UI on her phone and mentioned to her, "if the cameras don't load, open Tailscale and make sure it's connected". Works great - she hasn't complained about anything at all.

If you use Tailscale for everything, there's no need to have a reverse proxy. If you use Unraid, version 7 added the ability to add individual Docker containers to the Tailnet, so each one can have a separate Tailscale IP and subdomain, and thus all of them can run on port 80.

I use fail2ban to ban IPs that fall to login and also IPs that perform common scans in the reverse proxy
