#792: Password Reuse
[[A man is sitting facing a computer, Hat man is standing behind him.]]
Hat man: Password entropy is rarely relevant. The real modern danger is password reuse.
Man: How so?
(Computer: Password too weak.)
[[Close up on just Hat man.]]
Hat man: Set up a web service to do something simple, like image hosting or tweet syndication, so a few million people set up free accounts.
[[The man has now turned his chair around to face Hat man.]]
Hat man: Bam, you’ve got a few million emails, default usernames, and passwords.
[[Just Hat man.]]
Hat man: Tons of people use one password, strong or not, for most accounts.

[[Hat man facing man in chair again.]]
Hat man: So, here I sit, a puppetmaster who wants nothing from his puppets. – It’s the same problem Google has.

[[A man stands, his chair behind him, leaning his hands on the edge of a boardroom table with the Google logo on it. Behind it sit a woman with a bun and glasses and another man.]]
Man: Okay, everyone, we control the world’s information. Now it’s time to turn evil. What’s the plan?
Woman: Make boatloads of money?
[[The man stands with his hand on his head.]]
Man: We already do!
Voice off-screen: Set up a companywide CoD4: Modern Warfare tournament each week?
That’s not evil!
