Why Client-Side CSPRNG Matters
Online password generators that make server calls log your plaintext keys in web server access logs. SparrowX Keys runs 100% inside your browser using the W3C Web Cryptography API.
Generated strings reside solely in temporary browser heap memory. Closing this tab permanently purges all trace.
Uses the operating system's kernel entropy pool (/dev/urandom on Linux/macOS, BCryptGenRandom on Windows).
Disconnect your Wi-Fi or airplane mode. SparrowX Keys continues generating high-entropy seeds with zero network.

Unlimited CSPRNG passwords, Diceware passphrases, API tokens, and UUIDv4 generation with zero sign-up, zero telemetry, and zero cloud storage.
