Welcome to the top of cryptography. We have elliptic curves, crazy math and huge numbers.

As a German, our car companies are still shady. One word: Abgasskandal
Changing the default porta is security through obscurity, which is not security but just a waste of time. Don't rely on attackers "maybe not finding stuff" but rely on your stuff being secure, even if someone had all information about your network and system architecture.
For 2fa, the other commenter mentioned yubikey pam modules. Those are probably useful, but if you want to secure your ssh server, the best solution is to use ssh keys and disable password login. I can really recommend that as its one of the few things in security that improves both usability and security.
Megameters are sometimes used, that's not true.
Just needs a Chinese unification. Yeah probably unlikely.
That's cool. Sounds like a win for data security (How do I translate Datenschutz to English?)
When I think of Israel based Software Corps I think of NSO Group. And I don't like NSO Group. Am I unrightfully biased?
I associate X with the X.org display manager, wondering what a display manager would need a government I'd to authenticate me for.
Megameters are somewhat common in astronomy, for example when describing low orbital hights.
From a Cybersecurity point of view, I think this is a legit attack. Imagine a server that has many virtual machines, all of which automatically trigger the reinstall mechanism as fast as possible.
If there is not some kind of limitation on that rule, depending on how their mechanism works, you could cost the game creater a lot of money.
I find your comment to be a bit North America focused. Surely there are many places in the world where that stuff is handy.
Germany, studying Cybersecurity. They are used in astronomy through, only a hobby if me.
