10 Common Password Mistakes and How to Avoid Them
Every year, millions of accounts are compromised because of weak passwords. The most common passwords — "123456", "password", "qwerty" — can be cracked in milliseconds.
Here are the 10 most common password mistakes and how to fix each one.
1. Using a Dictionary Word
"elephant" can be cracked in seconds. There are tools that try every word in the dictionary. Fix: Use a passphrase of 3-5 random words: "elephant puzzle candle clock" is exponentially stronger.
2. Reusing Passwords Across Sites
One site gets breached, and hackers try that password on other sites. 65% of people reuse passwords. Fix: Use a password manager to generate and store unique passwords for every site.
3. Using Personal Information
Your name, birth year, pet's name, or anniversary — all guessable from social media. Fix: Use random character strings. If you must include personal info, obscure it completely.
4. Simple Character Substitutions
"P@ssw0rd!" looks clever, but hackers know these tricks. Substitution rules have been part of cracking tools for years. Fix: Make your password longer instead of more complex. Length > substitutions.
5. Using Keyboard Patterns
"qwerty", "asdfgh", "123456" — these are the first things hackers try. Fix: Avoid any sequential pattern on your keyboard.
6. Not Using Two-Factor Authentication
Even a strong password can be stolen. 2FA adds a second layer — a code from an app or a hardware key. Fix: Enable 2FA on all accounts that support it, especially email and banking.
7. Writing Passwords on Sticky Notes
A strong password on a post-it note stuck to your monitor isn't secure. Fix: Use a password manager with auto-fill. You only need to remember one master password.
8. Not Changing Default Passwords
Routers, IoT devices, and smart home gadgets often come with "admin/admin" as defaults. Fix: Change default passwords immediately after setup.
9. Making Passwords Too Short
A 6-character password can be cracked instantly. An 8-character one takes hours. A 12-character one takes centuries. Fix: Minimum 12 characters. For critical accounts, 16+.
10. Not Checking If You've Been Breached
Your password might already be public without you knowing. Fix: Use a service to check if your email or passwords appear in known data breaches.
