> .. why passwords? What do they do? What do they protect? They protect data/accounts on other machines. Similar to a piece of paper you'd write a password on but probably with added encryption, which would be difficult on paper. Want to sign into account XY on the internet connected machine? Just look up the password (which might be a hard to remember sequence of characters) on the air gapped password machine.
