Passwords are the first line of defense against hackers, but most people still make critical mistakes that put their accounts at risk.
A weak or mismanaged password can lead to identity theft, financial loss, or even complete account takeovers.
In this guide, we’ll cover the most common password mistakes and show you how to fix them.
❌ 1. Using Weak Passwords
Many people still use easy-to-guess passwords like:
- 123456
- password
- qwerty
- admin
yourname123
These passwords can be cracked in seconds using brute force attacks.
✅ How to Fix It:
- Use a minimum of 12-16 characters.
- Include uppercase, lowercase, numbers, and symbols (e.g.,
G!7x&4s#Qp). - Avoid dictionary words or personal details (birthday, pet name, etc.).
❌ 2. Reusing the Same Password on Multiple Sites
Using the same password across multiple accounts means that if one password is leaked, hackers can access all your accounts.
✅ How to Fix It:
- Use a unique password for each website.
- A password manager like Bitwarden, 1Password, or Dashlane can generate and store different passwords for you.
❌ 3. Using Short Passwords
Short passwords are easy to crack. A 6-character password can be broken in seconds.
✅ How to Fix It:
- Make passwords at least 12-16 characters long.
- The longer, the better, a 20-character password is significantly stronger than a 10-character one.
❌ 4. Not Using Two-Factor Authentication (2FA)
Even a strong password isn’t enough if hackers get access through phishing, leaks, or malware.
✅ How to Fix It:
- Enable Two-Factor Authentication (2FA) on important accounts (email, banking, social media).
- Use an authenticator app like Google Authenticator or Authy, instead of SMS (which can be hacked via SIM swapping).
❌ 5. Saving Passwords in Browsers or Notes
Storing passwords in your browser or writing them down in notes (on paper or phone) makes them easy to steal.
✅ How to Fix It:
- Use a password manager instead of saving passwords in your browser.
- If you must write passwords down, store them in a locked, secure location.
❌ 6. Not Changing Default Passwords
Devices like routers, security cameras, and smart home gadgets come with default admin passwords that hackers can easily find online.
✅ How to Fix It:
- Change default passwords immediately after setting up new devices.
- Use strong, unique passwords for each device.
❌ 7. Answering Security Questions with Real Answers
Hackers can easily guess or find answers to security questions (mother’s maiden name, first pet, city of birth).
✅ How to Fix It:
Use fake answers that only you know.
Example:
-
Q: What is your first pet’s name?
-
A:
PurpleBanana!24
Store these fake answers in a password manager.
❌ 8. Sharing Passwords with Others
Sharing passwords with friends, family, or coworkers increases the risk of leaks or unauthorized access.
✅ How to Fix It:
- Use shared access features instead of giving out passwords (e.g., Netflix, Google Drive, LastPass Families).
- If you must share, use a secure password manager instead of text or email.
❌ 9. Not Updating Compromised Passwords
If a password is leaked in a data breach, hackers will try it everywhere (email, banking, social media).
✅ How to Fix It:
- Check if your passwords have been leaked using Have I Been Pwned.
- If a password has been exposed, change it immediately.
✅ Final Security Checklist
✔ Use a strong, unique password for every account.
✔ Enable Two-Factor Authentication (2FA) on all important accounts.
✔ Store passwords securely in a password manager.
✔ Change passwords immediately if they are exposed in a breach.
✔ Avoid sharing passwords or saving them in insecure locations.
