I tried the following code and it did not work
I would love a code that works. thanks.
<?php
//Use user phone number as auto-generated password
function wcs_filter_password_phone_number( $args ) {
$args['user_pass'] = $args['dbem_phone'];
return $args;
}
add_filter( 'woocommerce_new_customer_data', 'wcs_filter_password_phone_number' );

Answer 1

It's not really secure setting the password based on the customer's phone number. Anyone could find a way in to be honest.
Having said that, the task is interesting, and based on WooCommerce: Update Order Field Value After a Successful Order it is possible indeed to alter an order/user field after a successful checkout.
You could hook into "woocommerce_thankyou" as per the article, or even into "woocommerce_payment_complete" if you wanted to do that in the background and only for paid/completed orders.
Also, you should look into https://developer.wordpress.org/reference/functions/wp_set_password/ which is the WP function to set a new password programmatically.
Here's my attempt:
add_action( 'woocommerce_thankyou', 'bbloomer_alter_password_after_order' );
function bbloomer_alter_password_after_order( $order_id ) {
$order = wc_get_order( $order_id );
$phone = $order->get_billing_phone();
$user_id = $order->get_user_id();
if ( $phone && $user_id ) {
wp_set_password( $phone, $user_id );
}
}
