Underrated explanation, you held it finally click for me. I consider myself a fairly educated person but just couldn't wrap my head around what made it so special. Correct me if i'm wrong but my understanding is the server uses the public key to encrypt a challenge code that can only be decrypted by your private key. You get an on device prompt to approve the process and the rest is done under the hood.
To go further on this, is the public/private key a mathematical relationship? What ties the two together to make them useful as a pair?
AudioBookShelf is a beautiful podcast option. OP would have to fully migrate into it but once done it'll let you listen to an episode on pc, pause, then resume from the same spot on mobile. It'll auto grab episode as they come out and store them on your system for streaming or local access. The android app is pretty good and i know webapp works well on ios
It gets even more automated/complex when you add in something like overseerr which pairs up with sonarr and radarr to read your library and allows your users to search for a title and request it if it's not in your library. With the click of an approve button the automation will have their desired title on plex in a matter of minutes.
I'm seeing a lot of good options involve email servers and if that's the best route then that's where i'll take things but i'd prefer nothing more than a simple, lightweight, calendar service.
What public services do you use that you think you'd want to self host? I'm trying to reduce the data i give to big companies so i starred running an instance of Audiobook-shelf and use it to auto grab my podcasts from an rss feed and keep a copy on my server plus it serves up all my audio books too. Or you could set up a vpn back to your network via wireguard and get the benefits of pihole when you're not home. If you feel like really digging into things you could host your own lemmy instance, or matrix chat and bridge in other serviced but that requires a bit more advanced knowledge.
Have you looked into syncthing?
