Having a single point of failure? I dunno. I already have mini hear attacks if I misplaced my phone because of all the data on it. My mails, my password manage

Having a single point of failure? I dunno. I already have mini hear attacks if I misplaced my phone because of all the data on it. My mails, my password manager etc. I really don't know if I would add my keys and my money to this. If lost, you literally are left with nothing.
