Stringent password rules lower risk of personal data breaches

Next, they extracted sets of emails and passwords from two large data sets that were published online and contained over 1.3 billion email addresses and password combinations. Based on email addresses belonging to a university’s domain, passwords were compiled and compared against a university’s official password policy. The findings were clear: Stringent password rules significantly lower a university’s risk of personal data breaches.
