Abstract: A computing system can associate a customer device of a customer with a financial transaction record and the merchant, the financial transaction record indicative of a first purchase from the merchant by the customer, transmit a first query to the customer device prompting the customer to input information regarding an aspect of the first purchase, the first query including a description of a predetermined product parameter of the financial transaction record indicative of the first purchase from the merchant by the customer, authenticating, by the computing system, the first request by determining that the customer-input response to the first query corresponds to the established aspect of the first purchase in accordance with a predetermined accuracy threshold, and authorizing, by the computing system, connection of the customer device to the network provided by the merchant based at least in part on the first request being authenticated.

Abstract: A computing system includes a network interface, a customer database, and a processing circuit. The processing circuit receives information indicative of a first purchase by a customer, establish an aspect of the first purchase as a network authentication credential for the customer, receive a first request to connect to the network from a customer device associated with the customer after completion of the first purchase, transmit a first query to the customer device prompting the customer to input information regarding the aspect of the first purchase, receive a customer-input response to the first query, authenticate the first request by determining that the customer-input response to the first query corresponds to the established aspect of the first purchase, and authorize connection of the customer device to the network based at least in part on the first request being authenticated.
