The coupon code is created in Shopify admin as Shopify instruction, and Better Coupon Box app reveals codes to customers in store's front end. Technically, Better Coupon Box alone cannot support one-time coupon code for each customer.
Fortunately, we have Bulk Discounts app - developed by Shopify (so it is FREE) - to work with Better Coupon Box to generate unique discount code for each customer.
