Hello
It is possible that when entering the shopping cart the payment options are shown as image1.
In addition, when you click on PROCESAR PEDIDO OR FINISH THE PURCHASE, a notice appears like image2 where the customer can continue as a guest or log in or enter with the tracks of Google or Facebook.
Unfortunately, Woocommerce does not provide the option. All the payment methods appear on the checkout page only. You will have to search for a plugin or customize Woocommerce.
