On this week’s episode of Converge, Google’s Mark Risher tells us why the conventional wisdom about choosing your password is wrong — and about the expanding number of threats faced by platforms like Gmail as they work to protect users from phishing attacks and spammers. Conventional wisdom about choosing longer, more complicated passwords is getting less effective over time. Meanwhile, the people behind phishing attacks are getting much better. Risher is a director of product management at Google, where he oversees Google’s identity, account security, and counter-abuse teams. A big part of Risher’s job over the years has been to fight unwanted email, and he says the methods used by spammers have evolved significantly over that time. Some attackers are getting much better results than they used to just by doing some research on their clients, he said. Risher tells us a better approach to picking passwords on Converge, an interview game show where the biggest personalities in tech tell us about their wildest dreams. It’s a show that’s easy to win, but not impossible to lose — because, in the final round, I finally get a chance to play and score a few points of my own.
