About Password Security

Entropy & Strength

Password entropy measures randomness in bits. A 20-character password with mixed characters has ~130 bits — practically uncrackable. Each bit doubles the number of guesses needed.

Passphrases

Passphrases use random dictionary words (e.g., "correct-horse-battery-staple"). They're longer, easier to remember, and very secure. A 5-word passphrase has ~65 bits of entropy.

Brute Force

Modern GPUs can test billions of password hashes per second. A short, simple password can be cracked in minutes. Length and complexity make brute force attacks infeasible.

Best Practices

Use a unique password for every account. Enable two-factor authentication. Use a password manager. Never share passwords. Change them if a breach occurs.
