What if they write it down in a single, centralizedz password manager? Which itself could be compromised?
That’s the only way I can keep the literally 100 accounts ive accumulated over the years straight, without reusing passwords.
And while I believe that is reasonably secure in my case, if that got compromised I’d be pretty screwed (well, 2fa would probably still limit the worst of it). But most people probably wouldn’t even be that secure about it.
