Frequently Asked Questions
Is the Password Generator free?
Yes, generate unlimited passwords and passphrases with no signup. All entropy calculations, crack-time estimates, and batch generation (up to 20 at once) are included free.
Are the passwords truly random?
Yes, we use the browser's crypto.getRandomValues() API which provides cryptographically secure randomness — the same standard used by security software.
What's the difference between random and passphrase mode?
Random mode creates strings like 'k$9Fv!2pLm' for maximum security. Passphrase mode creates memorable phrases like 'Castle-River-Phoenix-42' that are easier to remember but still very strong.
How long should my password be?
At least 12 characters for random passwords (16+ recommended) or 4+ words for passphrases. Our entropy display shows exactly how secure each password is.
What does the crack time estimate mean?
It estimates how long it would take to brute-force your password at 1 trillion guesses per second. Higher entropy = longer crack time = more secure.
Does the tool store my passwords?
No. Passwords are generated entirely in your browser and never stored, transmitted, or logged anywhere.
