I want to unlock the ability to view content on my mobile device. I can do that with a one-time purchase (payed with google opinion rewards) or with a subscription. I want to unlock the ability for my entire family though, across multiple devices. Do I have to pay the “one-time payment” for every device? If so, the plex subscription might be worth it. Is there any other major benefit to having a plex subscription?
My main bone to pick with Plex is that I believe that free and open source software should be gratis (free as in beer). You’re right about the authentication though. I have mine set up with a simple user name and password over http. I rely on the VPN to limit access to the network through a forwarded port. I don’t really like the idea of authentication being done on someone else’s machine for privacy reasons, which is why I choose jellyfin that runs on my local machine. I’m not currently sharing it, and if I did I would change some of my security practices.
