use-pwned-passwords v1.0.2

usePwnedPasswords custom hook

This is a custom React hook that adds support for checking password fields against Trow Hunt's Have I Been Pwned passwords API. Uses the hibp module for the heavy lifting.

Usage

import { usePwnedPasswords } from "use-pwned-passwords";

export const App = () => {
    const [passwordValue, pwnedCount, fieldProps] = usePwnedPasswords();

    return (
        <fieldset>
            {pwnedCount ? (
                <p className="error">
                    Your password has been found in {pwnedCount} breaches.
                    Please choose a more secure one.
                </p>
            ) : null}
            <label>
                Enter your password:
                <input type="password" {...fieldProps} />
            </label>
        </fieldset>
    );
};

The password is checked onBlur. The usePwnedPasswords() function can optionally take a config object. Currently there is one option you can set: defaultValue which sets the default value of the password field, but I'm not sure why you would set that.
