Re: Do you use one of these popular passwords?
That's shockingly high. Sadly not entirely unexpected though, I guess.
I know someone whose password involves running their finger along a keyboard row from left to right. He probably can't recall the actual characters. Dude struggles with passwords though, seems odd as he's otherwise a bright guy but I guess everyone has their nemesis.
A few times I've suggested he at least choose a pattern he can remember easily, and a memorable yet non-obvious modification scheme to apply to different sites, but he didn't go for it. An uncomfortable truth is some people just can't comprehend password security. It's simply beyond them.
