In this youth-oriented tech-savvy world, a new study finds that people over the age of 55 are far better at coming up with secure passwords than teens and young adults.  Joseph Bonneau, a computer scientist at the University of Cambridge, studied password data from 70 million Yahoo users.  He found the passwords of older adults are twice as strong as those under under 25.

He also found that those who change passwords frequently tend to have stronger passwords.
