I haven’t watched it, but I’ve heard Mobile Suit Gundam 0080: War in the Pocket is a pretty brutal anti-war piece by the end.

What you’re looking for is probably something like certificate authentication, or mTLS. It exists, but it’s kind of a pain to set up on client devices so it’s not very common.

What’s more common and easier to set up and is nearly the same thing, is passkey authentication. Same in-flight security characteristics, but you typically need to pass a simple challenge for your device to unlock it.

There are a bunch of self-hosted auth options for both

I wanna try matrix, but it’s crazy to me that no clients, even the official clients, support all the features. It really makes me hesitate lol

I’m nearly certain that nobody who died in WW2 is alive today
