Frequently Asked Questions
Quick answers to common questions
How random are generated passwords?+
Passwords use crypto.getRandomValues() — the browser’s cryptographically secure random number generator. Math.random() is never used.
What length should I use?+
Use at least 16 characters with all four character types for most accounts. Longer passwords resist brute-force attacks better.
Are my passwords stored or sent anywhere?+
No. Generation happens entirely in your browser. Passwords are never uploaded to any server.
What does exclude ambiguous characters do?+
It removes easily confused characters like 0, O, l, and 1 — helpful when passwords are read aloud or typed by hand.
Can I generate multiple passwords at once?+
Yes. Click Generate 10 passwords to create a batch, each with its own copy button.
How is strength calculated?+
Strength considers password length, character variety (upper, lower, numbers, symbols), and the size of the character pool you selected.
