Everybody knows that Minecraft Java edition will run on anything that can run Java, like a Raspberry Pi, for example. Well, you need a launcher to run Minecraft Java edition, and the Java launcher (which will run on anything) only supports Mojang accounts (see https://www.minecraft.net/en-us/download/alternative it still says "We got you covered!").

Contrary to what others said in this thread, I think that the communication has been quite poor for this use case, because the official communication insists on saying that the Java version will still be working, which is a lie: the Java launcher already stopped working for new customers (I met several people who bought Minecraft to use it on Raspberry Pi, and their money is lost, because their purchase doesn't allow them to create the necessary Mojang account), and it will also stop working for all existing accounts in a few weeks.

It was not so hard to decide to make is a FAQ and say "Sorry guys, we are dropping support for all the architectures which are not the top 3 ones, your game will stop working", instead of saying "Don’t worry – the only thing that’s changing is how you log in to the game! [...] Minecraft: Java Edition will stay exactly the same, and we’ll continue to update and support it in the future."

Luckily 3rd party launchers lile MultiMC work almost everywhere. MultiMc specifically is just so much better than the standard launcher. Really recommend checking it out

Second MultiMC, the best launcher by far and fantastic for managing multiple instances with different versions and modpacks.

My family just got into Minecraft so we started with Microsoft accounts. They worked fine in the Java launcher, on Linux, Windows, and Mac Os.

We've since moved to MultiMC as others have mentioned.

I might be missing something, but all of my family accounts are Microsoft accounts, and we use the Java launcher exclusively.

Think OP is saying that the Java launcher for MS accounts is not published for architectures such as ARM in the Raspberry Pi. So the only way to launch on such devices is to use the legacy Mojang launcher, which will cease working when Mojang accounts are no longer supported.

I've been running a Minecraft server for over 11 years. It's finally time to switch it to offline mode and roll my own in-game authentication via plugin. So please pirate the game and join the fun. :)

Will probably result in more griefing and rollbacks but oh well.

Could you please list which of the Java launchers from that download page is not working? I tried the Mac one just now, and it did work; it needed a right-click Open in order to launch, but after that it updated itself and launches with the normal double-click.
