Security FAQ
Yes. We use the browser's native `window.crypto.getRandomValues()` API, which generates cryptographically secure pseudorandom numbers (CSPRNG), completely immune to PRNG predictability.
Zero server interaction. Every single password is generated and processed entirely inside your browser sandbox. No logs, no telemetry, no tracking.
According to NIST Special Publication 800-63B, length and entropy surpass arbitrary complex symbols. A 4-word passphrase is significantly easier for humans to remember while computationally infeasible for attackers to brute-force.
It automatically strips visual lookalikes such as 0 (zero) vs O (capital o), 1 (one) vs l (lowercase L) vs I (capital i). Perfect for WiFi keys, mobile logins, and manual typing.
