When a parent of mine died, I accessed their computer (not password protected). It was still powered on and logged into gmail, facebook, and various other sites. I simply changed the passwords and wrote them down (I also had access to the cell phone in cases where 2FA was used -- but that was rare in my parent's case). Now many years later, I still have access. The sites have no idea that user is deceased and I have no intention of notifying them. I don't actively use the accounts, but log into them when I'm feeling nostalgic.
