Interesting information you bring us, my friend Fox! In my case, I am very afraid of emails or any form of storage, so I have an old typewriter inherited from the Cold War where I have transcribed the passwords letter by letter so I avoid printing them and having some information stored on them. But I will consider the possibility you mention here of a Flash drive. Best regards.
