We had my Dad’s password info and after he passed, his Steam acct pretty much passed over to my brother, since he was the one always using my Dad’s account anyways. We also have family sharing up, so we all still get to share from most of his games anyways.
I do wonder what they’ll do after an acct is 50-100+ years old and it’s still being used. Will they at some point start tying it to your SS# or find some other way to tie it to specific people?
