Need to add the login option in cart instead of checkout page.

Dear @Plethora,

We hope this message finds you well.

To create a login/register form, you may refer to the following guide:
https://www.businessbloomer.com/woocommerce-separate-login-registration/

Once the shortcode is generated, you can add it to the cart page as needed.

We hope this information is helpful. Should you have any further questions, please do not hesitate to reach out.

Best regards,
The 8Theme Team

Hi @Plethora,

Please take a closer look at the link we shared, here is the login form shortcode:

/**
 * @snippet       WooCommerce User Login Shortcode
 * @how-to        businessbloomer.com/woocommerce-customization
 * @author        Rodolfo Melogli, Business Bloomer
 * @compatible    WooCommerce 9
 * @community     https://businessbloomer.com/club/
 */
  
add_shortcode( 'wc_login_form_bbloomer', 'bbloomer_separate_login_form' );
  
function bbloomer_separate_login_form() {
   if ( is_user_logged_in() ) return '<p>You are already logged in</p>'; 
   ob_start();
   do_action( 'woocommerce_before_customer_login_form' );
   woocommerce_login_form( array( 'redirect' => wc_get_page_permalink( 'myaccount' ) ) );
   return ob_get_clean();
}

Hope it helps!
