I've thought of this as well. Quite a bit. I have 4 devices I need to format. My Android phone. My iPad, my laptop and the hard drive connected to my Android TV. I'm probably going to attempt partial hanging soon. I remember 1 user posting a thread about taking a hammer to their laptop and phone. I don't want to do that because I want this stuff to be used by my family if possible.
It's not really going to matter because they're pretty well to do, but whatever. I'm not going to format anything because I'm afraid of surviving and then I have to deal with the data loss. It's not a joke since my company requires multi factor authentication etcetera to log into my worksites. i don't want to have to deal with all that. I'll just make sure no one else can log in to any of my devices without having to format it. I'll set complicated pass codes for them. No biometrics.But yeah, just make sure to clear all your browser history etcetera.
