A disclaimer first: please make sure this is legal in your country and also that your checkout visitors are aware they will become registered customers without explicit consent (i.e. without ticking a “create an account on this site” checkbox).
So, yeah, there is a way to turn guest checkouts into registered customer ones. Also, there is a neat WooCommerce function to bulk add all past guest orders to a new customer (wc_update_new_customer_past_orders).
Of course, “Allow customers to place orders without an account” must be enabled in your WooCommerce settings, otherwise you’re not allowing guest checkouts and the snippet will be irrelevant.
So, here’s the fix. Enjoy!
PHP Snippet: Automatically Register Guest Customers @ WooCommerce Checkout (and Programmatically Log Them In @ WooCommerce Thank You Page)

add_action( 'woocommerce_thankyou', 'bbloomer_register_guests', 9999 );
function bbloomer_register_guests( $order_id ) {
$order = wc_get_order( $order_id );
$email = $order->get_billing_email();
if ( ! email_exists( $email ) && ! username_exists( $email ) ) {
$customer_id = wc_create_new_customer( $email, '', '', array(
'first_name' => $order->get_billing_first_name(),
'last_name' => $order->get_billing_last_name(),
));
if ( is_wp_error( $customer_id ) ) {
throw new Exception( $customer_id->get_error_message() );
}
wc_update_new_customer_past_orders( $customer_id );
wc_set_customer_auth_cookie( $customer_id );
} else {
$user = get_user_by( 'email', $email );
wc_update_new_customer_past_orders( $user->ID );
wc_set_customer_auth_cookie( $user->ID );
}
}
Thanks for This! Really helps a lot! I just want to know if you have a related tutorial where order from guest checkout can be sync if customer created an account? Thank you!
Hey Jovan, wc_update_new_customer_past_orders() function already does that
If this Snippet removes the Create account password on checkout, then how would the customer access their account?
Hi Brooke! wc_create_new_customer should already email account details to customer – please test and let me know
