Ask Sarah Palin how that worked out for her. The flaw is that you aren't the only person who knows the answer to these questions. It's not just the public figures who are vulnerable. We're all Googleable, and those #TBT posts on Facebook and Twitter could give away a lot about your early years. Someone who's determined to get access to your email can do a little research and unlock your account.
Lie and keep telling the same lie
My trick? Lie and keep telling the same lie.
What's your favorite ice cream flavor? Louis Armstrong.
What was the name of your high school? Louis Armstrong.
In what city did you have your first job? Louis Armstrong.
Don't give correct answers. Use the same stupid answer for all of your security questions. (If you're worried you'll forget the stupid answer, store it in a password manager.)
Password dance
Stupid password trick No. 2 was inspired by a friend's tweet:
The password dance: 1) buy something, 2) forced to create account, 3) set password, 4) weeks go by, 5) go back, 6) forgot password, 7) reset
My first reaction to this was, "Why aren't you using a password manager?" But the more I thought about this, the more I think this password dance is really a simple method of implementing something like one-time passwords. Why use a memorable password at all?
Choose something really random, don't worry about saving it or remembering it, and force the site to re-authenticate you through email!
You get security without the need to add random sites to a password vault and don't need to install LastPass or anything new.
