Common Password Mistakes That Get Accounts Hacked

Learn about the most common password mistakes people make and how to fix them to keep your accounts secure.

Common Password Mistakes That Get Accounts Hacked

Despite widespread awareness of password security, people continue to make the same mistakes. This guide covers the most common password errors and how to fix them.

Mistake 1: Using Weak Passwords

The Problem: The most common passwords are still "123456", "password", and "qwerty". Why It's Dangerous: These passwords appear in every password cracking dictionary. They can be cracked in under a second. The Fix:
    • Use at least 16 characters
    • Mix uppercase, lowercase, numbers, and symbols
    • Generate random passwords with our Password Generator

Mistake 2: Reusing Passwords Across Sites

The Problem: 65% of people use the same password for multiple accounts. Why It's Dangerous: When one site gets breached, attackers use those credentials on other sites (credential stuffing). One breach can compromise your email, banking, and social media. The Fix:
    • Use a unique password for every account
    • Use a password manager to track them
    • Generate unique passwords with our Password Generator

Mistake 3: Using Personal Information

The Problem: Using names, birthdays, pet names, or phone numbers in passwords. Why It's Dangerous: This information is easily found on social media. A targeted attack can guess these passwords quickly. The Fix:
    • Never use personal information in passwords
    • Use randomly generated passwords instead
    • If you must create your own, use a passphrase technique

Mistake 4: Making Minor Variations

The Problem: Changing a password from "Password1!" to "Password2!" to "Password3!" Why It's Dangerous: Attackers know people do this. Their algorithms try these variations automatically. The Fix:
    • Generate completely new passwords, not variations
    • Each password should be entirely different
    • Use our Password Generator for truly random passwords

Mistake 5: Sharing Passwords Insecurely

The Problem: Sending passwords via email, text message, or chat apps. Why It's Dangerous: These messages can be intercepted, logged, or stored on servers indefinitely. The Fix:
    • Use password manager sharing features
    • Use encrypted messaging for temporary sharing
    • Never send passwords in plain text

Mistake 6: Ignoring Two-Factor Authentication

The Problem: Not enabling 2FA/MFA even when it's available. Why It's Dangerous: Even with a strong password, a phishing attack or keylogger can compromise your account. 2FA adds a second layer that stops most attacks. The Fix:
    • Enable 2FA on every account that supports it
    • Use an authenticator app (not SMS) when possible
    • Use hardware security keys for critical accounts

Mistake 7: Storing Passwords Insecurely

The Problem: Writing passwords on sticky notes, in spreadsheets, or in browser autofill without a master password. Why It's Dangerous: Physical notes can be photographed. Spreadsheets can be stolen. Browser autofill without encryption is a goldmine for malware. The Fix:
    • Use a password manager with encryption
    • Enable a strong master password
    • Use biometric unlock on mobile devices

Mistake 8: Using Short Passwords

The Problem: Using 8-character passwords because a website's minimum is 8. Why It's Dangerous: 8-character passwords can be cracked in hours, even with complexity requirements.
LengthTime to Crack (mixed charset)
8 chars~2 hours
10 chars~6 months
12 chars~226 years
16 charsTrillions of years
The Fix:
    • Always use 16+ characters
    • If a site limits length, use the maximum allowed

Mistake 9: Not Checking for Breaches

The Problem: Continuing to use passwords that have been exposed in data breaches. Why It's Dangerous: Breached passwords are sold and traded by criminals. Yours may already be compromised without you knowing. The Fix:
    • Check your email at Have I Been Pwned
    • Use password manager breach monitoring
    • Change any password that appears in a breach

Mistake 10: Changing Passwords Unnecessarily

The Problem: Forced password rotation leads to weaker passwords, not stronger ones. Why It's Dangerous: People create predictable patterns when forced to change passwords frequently (Spring2024!, Summer2024!, etc.). The Fix:
    • Only change passwords when:
- There's a suspected breach - You shared it with someone who no longer needs access - You used it on an untrusted device
    • NIST guidelines now recommend against forced rotation
