Total Defense Security Tip of the Day
06.28.25
The best way to use security questions for online accounts
We've all encountered them: those nagging security questions when you're setting up an account or trying to reset a forgotten password. "What's your mother's maiden name?" "What was the name of your first pet?" "What city were you born in?" It feels like a quick and easy way to recover your account if you get locked out. But here's the dirty little secret: if you answer them truthfully, you might be creating a massive security hole!
Think about it: so many of those traditional security questions rely on information that's surprisingly easy for a determined cybercriminal to find out about you. Your mother's maiden name might be public record or even visible on her social media profile. The name of your first pet? Probably in an old Facebook post from five years ago. Your birth city? Easy to find online, especially if you're not super private. This publicly available information can be a goldmine for hackers trying to impersonate you and bypass your password. It's like having a "secret" handshake that everyone already knows!
The Big Problem with Common Security Questions:
- Publicly Available Information: We share so much online these days. A quick search of your social media, old news articles, or public records can reveal answers to many common security questions.
- Social Engineering Goldmine: Hackers are experts at "social engineering." They'll use bits of information they find about you to craft convincing stories or guess your answers, tricking systems into believing they're you.
- Limited Options: The pool of common answers for questions like "What's your favorite color?" or "What's your high school mascot?" isn't infinite, making them easier to guess, especially with automated tools.
- Identity Theft Risk: If an identity thief already has some of your basic personal info (from a data breach, for example), those security questions can be the final puzzle pieces they need to unlock your accounts.
The Smart Strategy: Treat Them Like Extra Passwords!
Instead of giving a factual answer to a security question, treat it like another unique, strong password. Make up a completely random, memorable (to you!) answer that has absolutely no relation to the actual truth.
Here's how to do it effectively:
- Be Creative and Random:
- Question: "What was your first pet's name?"
- Bad Answer (Truthful): "Buddy" (easy to guess if someone knows you)
- Good Answer (Made Up): "BlueBananaCar!#" or "MoonLandingWasFake78"
- Mix It Up: For "What city were you born in?", don't use your actual birth city. Instead, invent something like "InvisibleCastle" or "PurpleOctopusLand."
- Use a Password Manager (Seriously!): This is the key to making this strategy work. Since you're making up answers, you cannot rely on your memory. Your password manager is the perfect, secure place to store these made-up security question answers right alongside your passwords for each specific account. It's an encrypted vault for all your digital secrets.
- Avoid Patterns Based on Real Info: Don't create made-up answers that are just slight variations of your real information (e.g., if your real pet was "Fido," don't use "Fido123"). Go completely random!
By transforming your security questions into unguessable, made-up "fibs," you're building a much stronger defense against account takeovers. You're ensuring that even if someone manages to find out personal facts about you, they won't be able to use them to bypass your security. It's a simple change that makes a huge difference in protecting your digital life. Start fibbing for your security today!
