How it works

We use the browser's secure random source (Web Crypto) and guarantee at least one character from each enabled set.

Formula

Weighted random selection from the chosen sets (lower/upper/digits/symbols).

Worked example

16 chars with all options yields a very strong, hard-to-crack password.
