McGruber writes "Joseph Bonneau, a computer scientist at the University of Cambridge, calculated the password strengths of nearly 70 million Yahoo! users. He compared the strengths of passwords chosen by different demographic groups and compared the results. People over the age of 55 pick passwords double the strength of those chosen by people under 25 years old." Does this mean that the younger users are more cavalier and naive, or are they simply more cynical about the actual value of strong passwords in the era of large-scale user-database compromises?
