Entropy Score
What is entropy? Entropy measures password randomness in bits. Each additional bit doubles the keyspace, making brute-force attacks exponentially harder. Aim for 60+ bits; 80+ is effectively uncrackable.

Learn About Password Security
What Makes a Password Strong?
Length beats complexity. A 16-character passphrase is stronger than an 8-character scramble. Each extra character exponentially increases crack time.
Minimum 12 characters — 16+ is better
Mix of uppercase, lowercase, numbers, symbols
Avoid dictionary words and predictable patterns
Never reuse passwords across different sites
Pro tip: Use a passphrase like "correct horse battery staple" — memorable yet strong.
Common Password Mistakes
Using "password", "123456", or "qwerty"
Personal info: names, birthdays, pet names
Keyboard patterns: abc123, !@#$%^and*
Short passwords (under 12 characters)
Reusing the same password everywhere
Warning: "Trent123!" takes less than 1 second to crack — even with the exclamation mark.
Password Manager Tips
A password manager is the single best thing you can do for your security. Here's how to pick and use one effectively:
Use Bitwarden, 1Password, or Dashlane
Generate unique 20+ character passwords per site
Enable biometric unlock on mobile devices
Share passwords safely via the manager
Audit existing passwords for duplicates regularly
Best practice: Use a strong master password, then let the manager handle everything else.
