What Makes a Strong Password?

In 2025, a simple 8-character password can be cracked purely by brute force in less than an hour. A strong password leverages entropy—mathematical randomness.

  • Length is King: Every additional character exponentially increases the difficulty to crack. A 16-character password is trillions of times stronger than an 8-character one.
  • Variety Matters: Using symbols ($#@), numbers, and mixed case letters expands the possible combinations.
  • Unpredictability: Humans are bad at being random. We use patterns (like "Password123"). A computer generator removes these patterns.

Common Password Mistakes

❌ using Personal Info

Avoid names of pets, birthdays, or street names. These are the first things hackers guess.

❌ Reusing Passwords

Never use the same password for multiple sites. If one site is breached, all your accounts are at risk.
