Google and computer scientists at Stanford University conducted a study of words used for security questions for online accounts found that many supposedly secure words are a lot less secure than people think. They found hackers could probably guess the answers with ease. For example, a hacker would have a 20% chance of guessing the right answer by answering “pizza” to the question “What’s your favorite food?” Given ten guesses would give an attacker a 21% chance of guessing a Spanish-speakers’ father’s middle name.—Jim L.

Being able to predict a word 20% of the time is impressive, but some words you can count on 100% of the time.
