alt Hacker NewsRE: Sea of Thieves on linux w/ xb/microsoft auth. I was able to work around it by just removing 2fa from my microsoft acc. Obviously not a great solution. but yeah. You may be able to reenable it afterwards, I never tried, its the only thing my microsoft account is useful for at this point anyways.
Orly? I hadn't gotten that far yet but interesting data point. I'd only tried Infinite and the game just wouldn't even really launch, I didn't even get to the main menu, didn't open XBox authentication at all and I just assumed I had to have something installed. When I did some googling I'd heard of something called... my memory fails me, Heroic I think? I hadn't actually gotten around to trying yet though so I've no clue if that's any good.
