Not really a big deal for me but I looked around and couldn’t find anything sadly. My media is generally 2k with a larger phone it hasn’t hit me to hard to switch seasons in and out (as they allow bulk downloads of seasons). Certainly would be a good feature I’d say!

I’d say it’s nearly as secure as

basic authentication. If you restrict deletion to admin users and use role (or group) based auth to restrict that jellyfin admin ability to people with strong passwords in keycloak, i think you are good. Still the only risk is people could delete your media if an adminusers gmail is hacked.

Will say it’s not as secure as restricting access to vpn, you could be brute forced. Frankly it would be preferable to set up rate limiting, but that was a bridge too far for me

I am using tailscale but I went a little further to let my family log in with their Gmail( they will not make any account for 1 million dollars)

Tailscale funneled Jellyfin Keycloak (adminless)

Private Tailscale Keycloak admin Postgres dB

I hook up jellyfin to Keycloak (adminless) using the sso plugin. And hook Keycloak up (using the private instance) to use Google as an identity provider with a private app.

I’m doing it on my android. Don’t have an iPhone to debug sadly. I click on the three dots next to the episode and it is an option there. Just checked and I can also do it by the season. I am on an administrator account

Maybe I’m not understanding offline downloads, but I’m able to download media on jellyfin and watch it offline.
