WooCommerce 2.1 Add confirm password option at checkout

functions.php

<?php
// place the following code in your theme's functions.php file
// Add a second password field to the checkout page.
add_action( 'woocommerce_checkout_init', 'wc_add_confirm_password_checkout', 10, 1 );
function wc_add_confirm_password_checkout( $checkout ) {
	if ( get_option( 'woocommerce_registration_generate_password' ) == 'no' ) {
		$checkout->checkout_fields['account']['account_password2'] = array(
			'type' 				=> 'password',
			'label' 			=> __( 'Confirm password', 'woocommerce' ),
			'required'          => true,
			'placeholder' 		=> _x( 'Confirm Password', 'placeholder', 'woocommerce' )
		);
	}
}

// Check the password and confirm password fields match before allow checkout to proceed.
add_action( 'woocommerce_after_checkout_validation', 'wc_check_confirm_password_matches_checkout', 10, 2 );
function wc_check_confirm_password_matches_checkout( $posted ) {
	$checkout = WC()->checkout;
	if ( ! is_user_logged_in() && ( $checkout->must_create_account || ! empty( $posted['createaccount'] ) ) ) {
		if ( strcmp( $posted['account_password'], $posted['account_password2'] ) !== 0 ) {
			wc_add_notice( __( 'Passwords do not match.', 'woocommerce' ), 'error' );
		}
	}
}
?>

Works great. An improvement would be if JavaScript would validate the equality before submission.

Cool. Thank you very much.

Thank You very much

How can we render placeholder and label multilingual ?

Many thanks! Exactly what i was looking for. works like a charm

I'm not getting the passwords to validate each other. You can type in two different passwords and it allows someone to checkout. Anyone know how to fix?

I was using stripe modal checkout, the popup that takes the credit card, when I turned that off and allowed the user to enter cc number directly on site then it worked.

Stopped working for me in WC 3 - passwords so not match error
