You’re the second person writing about this. I think it varies by country? Like… for how I see it, other than my car I don’t plan on having other loans. As for bank accounts and other financial stuff I think there is some kind of process that starts once the death has been announced in some formal way. Everything else should just be forgotten. Like just do what people did in the 50s or sum. There was no common technology in which to store important stuff. Just do the same things as back then for whatever matters, everything else is in my phone and pc shouldn’t be so crucial.
I see the curiosity. For me though unless it’s some pictures we took together (which I would have shared with them in the first place) the rest is stuff only me and whoever was involved should remember. As I said in another reply, if I didn’t share it it’s because I didn’t need/want to in the first place.
