FAQ
Common questions about the password generator.
Is this password generator secure?
Yes. Passwords are generated with the browser’s cryptographic random number generator (crypto.getRandomValues) and never leave your device.
Are generated passwords stored or sent anywhere?
No. Everything happens locally in your browser. Once you close the page, the passwords are gone.
How does the strength meter work?
Points are awarded for length (8+ and 12+ characters), mixed case, numbers and symbols. Under 50 is Weak, 50–74 is Medium, 75+ is Strong.
Why does “Generate 5 More” exist?
It instantly creates five passwords with the same settings — handy when one password is rejected by a service or you need to rotate several accounts.
What password length should I use?
Aim for at least 12 characters mixing lowercase, uppercase, numbers and symbols. For critical accounts, 16 or more is better.
How is this different from Math.random()?
crypto.getRandomValues is a cryptographically secure generator, making the passwords far harder to predict than Math.random().
