What CSPRNG means here
A cryptographically secure RNG — the browser’s getRandomValues, not predictable Math.random. Same controls as the password generator hub.
FAQ
Math.random?
Never. Web Crypto getRandomValues only.
Why keep ambiguous chars on?
This page leans “full random charset”. For typing/print, enable exclusion or use the strong preset.
Where is entropy?
Bits and a strength label under the result — approx. length × log₂(charset size).
Leaves the device?
No. Copy once, then close the tab.
