Quick answers to common questions
Passwords use crypto.getRandomValues() — the browser’s cryptographically secure random number generator. Math.random() is never used.
Use at least 16 characters with all four character types for most accounts. Longer passwords resist brute-force attacks better.
No. Generation happens entirely in your browser. Passwords are never uploaded to any server.
It removes easily confused characters like 0, O, l, and 1 — helpful when passwords are read aloud or typed by hand.
Yes. Click Generate 10 passwords to create a batch, each with its own copy button.
