If you forget the password for an online account, what do you do? You click the "Forgot password" link. Often this takes you to a security question you arranged in advanced. Supposedly by correctly answering the question, you prove to the site that you are the rightful user to get access to the account.
Security questions are usually questions about your life, like "What was the name of your first pet?", "Where were you born?" and similar things. But there's just one big problem. Unfortunately, security questions are a huge security hole.
Google has looked at millions of security questions and the answers users picked. It found that security questions aren't a good idea. Either people choose the easiest questions and provide answers that are easily guessed (20% of Google users answered the question "What is your favorite food?" with "Pizza"), or they choose a question and answer so hard they couldn't remember it (For the question "What's your frequent flyer number?" only 9% of people remembered it correctly).
Google's recommendation is that companies switch over to security systems like two-step verification instead. Click here to learn how two-step verification works and how you can use it today on Google, Facebook and other popular sites.
