I would say the easiest and most beautiful website Backup Diary, the price is reasonable and the design is simple and elegant, I love this and going to share it with my loved ones as well.
I believe it would be very beneficial for older like our grandparents, sick people, and wealthy person because they really need this kind of diary to keep their important information in this, and in case they are no more in this world their family or friends will get to know about passwords and all.
