Frequently asked questions
How long should my password be?
Length matters more than anything else. Aim for at least 16 characters and mix in several character types; the longer and more varied the password, the harder it is to crack. A password manager paired with a long random string like this is the ideal combination.
Are these passwords really random?
Yes. Each character is chosen with crypto.getRandomValues, the browser's cryptographically secure random generator, rather than the predictable Math.random β so the output is suitable for real passwords and secrets.
Is the password sent anywhere?
No. Passwords are generated locally in your browser and are never transmitted, logged or stored β nothing leaves your device, so it is safe to copy the result straight into your password manager.
