The Exponential Power of Length

Adding one character doesn't make it a little harder. It makes it exponentially harder.

  • 6 characters (lowercase): 300 million combinations. Cracked instantly.
  • 7 characters: 8 billion combinations. Cracked in seconds.
  • 8 characters: 200 billion combinations. Cracked in minutes.
  • 12 characters: Trillions of combinations. Takes years.

Common Mistakes

  1. Substitutions: Swapping 'a' for '@' or 'i' for '1'. Hackers know these. 'P@ssw0rd1' is weak.
  2. Patterns: '123456', 'qwerty', 'asdfgh'.
  3. Personal Info: Dog's name + Birth Year. Social engineering makes this easy to guess.

The Solution: Password Managers

Stop remembering passwords. Use a manager (like 1Password or Bitwarden) to generate unique, 20-character nonsense for every site. You only need to remember ONE strong master password.

Security FAQs
