API Reference

PasswordStrengthInput

Renders a password input with a visibility toggle, a strength meter announced via a polite live region, and a requirements checklist. Pass value to control it from outside, or defaultValue to let it manage its own state. Strength is scored against rules, an array of PasswordRule objects of the shape { label: string; test: (value: string) => boolean }. The exported DEFAULT_RULES check for at least 8 characters, one uppercase letter, one number and one symbol.
