about this tool

Generates passwords with crypto.getRandomValues using rejection sampling (no modulo bias) and Fisher–Yates ordering. Character sets are toggleable and the entropy bar updates live.

Length beats symbol soup: 20 characters of mixed case + digits outranks most punctuated 12-character patterns.
