FAQ
How random are the generated passwords?
Our passwords use cryptographically secure random generation, making them extremely difficult to crack. A 16-character password with all character types has over 95 bits of entropy.
What's the recommended password length?
We recommend at least 12 characters for general use, 16+ for sensitive accounts. Longer passwords are exponentially more secure.
Is this tool safe to use?
Yes, all password generation happens locally in your browser. No passwords are transmitted or stored on our servers.
