A reader shares a BetaNews report: A new report by LastPass -- The Password Expose -- reveals the threats posed, and the opportunities presented, by employee passwords. The report starts by pointing out that while nearly everyone (91 percent) knows that it is dangerous to reuse passwords -- with 81 percent of data breaches attributable to "weak, reused, or stolen passwords," more than half (61 percent) do reuse passwords. But the real purpose of the report is to "reveal the true gap between what IT thinks, and what's really happening." Jumping straight into the number, the report says that even in a 250-employee company, there are an average of 53,250 passwords in use -- a near-impossible number to keep track of and to know the strength of. LastPass found that people have nearly 200 passwords to remember, so it's little wonder that password reuse is an issue.
