Question 3

How long should a password be?

Accepted Answer

For most accounts, 16+ random characters with mixed case, numbers, and symbols provides excellent security (over 90 bits of entropy). For highly sensitive accounts (banking, email), use 20+ characters or a passphrase of 5+ random words. The most important factor is uniqueness — use a different password for every account, managed with a password manager.

Question 4

Is this password generator secure?

Accepted Answer

Yes — this tool uses the browser's built-in crypto.getRandomValues() API, which is a cryptographically secure random number generator (CSPRNG). Passwords are generated entirely in your browser — nothing is sent to any server. You can verify this by using the tool offline after the page loads.

Question 5

What makes a password truly secure?

Accepted Answer

Length is more important than complexity. A 16-character random password with letters only has more entropy than a 10-character password with mixed characters. Entropy (bits) = log₂(character_set^length). For real security: use 16+ characters, truly random generation (not patterns or phrases you invented), a unique password for every account, and a password manager. A 20-character random password with full character set has ~131 bits of entropy — computationally infeasible to crack.

Question 6

What is a passphrase and is it more secure than a password?

Accepted Answer

A passphrase is multiple random words: 'correct-horse-battery-staple'. A 4-word passphrase from a 7,776-word Diceware list has ~51.7 bits of entropy. A 6-word passphrase has ~77.5 bits — equivalent to a strong 12-character random password but far more memorable. The key: words must be randomly chosen (not a meaningful phrase you composed), and ideally separated by special characters or numbers.

Question 7

What is password entropy?

Accepted Answer

Entropy (bits) = log₂(pool_size^length). Pool sizes: 26 lowercase = 4.7 bits/char. 52 upper+lower = 5.7 bits/char. 62 alphanumeric = 5.95 bits/char. 94 printable ASCII = 6.55 bits/char. Crack time at 10 billion guesses/second: 40 bits = instant, 60 bits = ~36 years, 70 bits = ~37,000 years, 80 bits = practically impossible. Modern GPU clusters crack billions of weak hashes per second, making password length the most critical factor.
