Frequently Asked Questions
How secure is this password generator?
Very secure. It uses crypto.getRandomValues(), the browser's cryptographically secure random number generator, not Math.random().
How long should my password be?
Use at least 16 characters for important accounts. 20+ characters is excellent. Length is the single most important factor in password security.
Are my generated passwords saved anywhere?
No. Passwords are generated locally and never sent to any server. They exist only in your browser session.
How can I check if my existing passwords are strong?
Use the Password Strength Checker to test your existing passwords and get security suggestions.
