What Makes a Password Strong?

Password strength comes down to entropy — the number of possible combinations an attacker must try. A 12-character password using uppercase, lowercase, digits, and symbols has roughly 79 bits of entropy. That's billions of years of brute-force time with current hardware.

Length Beats Complexity

Adding one character to a password does more for security than replacing a letter with a symbol. A 20-character lowercase password (abcdefghijklmnopqrst) has more entropy than an 8-character mixed password (P@55w0rd). The math is clear: length wins.

Common Password Mistakes

  • Predictable patterns — Password1! satisfies most policies but is trivially crackable
  • Personal info — names, birthdays, pet names are in every attacker's dictionary
  • Reusing passwords — one breach exposes all your accounts
  • Short passwords — anything under 12 characters is increasingly vulnerable

Generate Passwords Instantly

Use the Password Generator on CodeKitLab to create cryptographically random passwords with your choice of length and character set. Everything runs in your browser — nothing is sent to any server. Need random strings for API keys or tokens? The Random String Generator gives you full control over charset and quantity.

Passphrase Method

For passwords you need to type manually, use passphrases: 4-6 random words like correct-horse-battery-staple. They're long (high entropy) but memorable. Add a number and symbol if the system requires mixed characters.

Storage and Management

  • Use a password manager — one master password secures everything
  • Enable 2FA wherever possible
  • Never store passwords in plain text, .env files without encryption, or code repos
  • For hashing passwords in your apps, use bcrypt or Argon2 — verify hashes with the Hash Generator

Security starts with strong, unique passwords. Stop reusing weak ones — generate a proper one in two seconds and move on.
