Frequently asked
How is this different from the Password Generator?
The Password Generator is opinionated (cryptographic, entropy meter, ambiguity-avoidance). This tool is a lower-level utility: any charset, any prefix, no strength UI.
What is "cryptographic randomness"?
crypto.getRandomValues — the browser CSPRNG used for TLS handshakes. Off: Math.random (fast, not for secrets).
What is the max length and count?
Length up to 512 chars per string, up to 1000 strings per batch. Ample for API keys, seed data, and test tokens.
