Frequently asked questions
Is this password generator secure?
Yes. It uses the browser's built-in crypto.getRandomValues() — a cryptographically secure pseudorandom number generator (CSPRNG). Math.random() is never used.
Are my passwords stored or sent anywhere?
No. Generation happens entirely in JavaScript running in your browser tab. Nothing is transmitted to any server.
What password length should I use?
At least 16 characters for most accounts. For high-value accounts or master passwords, 24+ characters is recommended.
Should I include symbols?
Yes, if the service allows it. Symbols significantly increase the character space, making brute-force attacks exponentially harder.
What does "exclude ambiguous characters" do?
It removes characters like 0, O, 1, l, and I that look similar in many fonts — reducing the chance of copy errors when typing manually.
Can I generate multiple passwords at once?
Yes — click Generate repeatedly, or enable auto-generate to produce a new password every time you change a setting.
