Password Security

Your First Line of Defense

Why Password Security Matters

Passwords are the keys to your digital life. Weak passwords are responsible for 81% of data breaches. Yet most people still use easily guessable passwords like "123456" or "password" - the same ones that top the list year after year.

A single compromised password can lead to identity theft, financial loss, and access to your other accounts through password reuse. Understanding password security is the foundation of your digital defense.

Common Password Mistakes

Avoid These Critical Mistakes

These habits make your accounts vulnerable to attack.

  • Password reuse - Using the same password across multiple sites
  • Personal information - Names, birthdays, pet names in passwords
  • Dictionary words - Single words found in any dictionary
  • Simple patterns - Sequential numbers, keyboard patterns (qwerty)
  • Short passwords - Anything under 12 characters
  • Minor variations - Password1, Password2, Password!

Creating Strong Passwords

A strong password should be long, random, and unique to each account. Here are proven methods:

Method 1: Passphrase

Combine 4-6 random words into a phrase. This creates passwords that are both secure and memorable.

passphrase-example
correct-horse-battery-staple
purple-elephant-dancing-rainbow-42
coffee!mountain$river#sunset

Method 2: Random Generation

Use a password manager to generate truly random passwords of 16+ characters.

Password Managers

A password manager is essential for modern security. It generates, stores, and fills strong unique passwords for every account.

One Password to Remember

With a password manager, you only need to remember one strong master password. The manager handles the rest.
