Not to sound like a Steam simp, but they put a lot of faith in Steam Guard. Gabe Newell shared his password. This is old information and he may have changed it, also I don’t know if there were problems. https://www.escapistmagazine.com/gabe-newell-gives-away-personal-steam-password/

It’s not a good comparison, but it is funny to talk about. The founder of LifeLock trusted his product so much that he put his SSN on billboards and television ads. His identity was stolen 13 times. https://www.wired.com/2010/05/lifelock-identity-theft/
