Frequently Asked Questions
What is window.crypto and why does it matter?
window.crypto.getRandomValues() is the browser's cryptographic random number generator. Unlike Math.random(), it cannot be predicted or reproduced — making passwords generated with it genuinely secure.
Can I generate multiple passwords at once?
Yes. Select a quantity (1, 5, 10, or 25) and click Generate. Copy all passwords at once for batch account creation or password rotation.
What characters should a secure password include?
A secure password should include uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). Enable all character sets in the generator for maximum security.
Should I use a password manager with generated passwords?
Absolutely. Generated passwords are strong but hard to memorize — a password manager like Bitwarden, 1Password, or KeePass stores them securely so you only need to remember one master password.
