Multi-device authorization

A method of multi-factor transaction authentication utilizing a plurality of devices, the method comprising:

• receiving, by at least one server of a checkout service, from a browser device via an interactive purchase interface accessed via the browser device, a request to process a transfer of a payment amount for a transaction between a customer and a merchant, wherein login information associated with a login via the browser device into the interactive purchase interface serves as a first indicator of authorization for processing of the transfer of the payment amount for the transaction;
• generating, by the at least one server of the checkout service, an optical code that optically encodes information pointing to an interactive authorization interface, wherein the interactive authorization interface is to serve as a second indicator of authorization for the processing of the payment amount for the transaction;
• causing, by the at least one server of the checkout service, the optical code to be displayed via the interactive purchase interface as accessed via the browser device;
• receiving, by the at least one server of the checkout service, an indication that a scanning device has used a camera of the scanning device to optically scan the optical code as displayed via the interactive purchase interface that is accessed via the browser device and that the scanning device has accessed the interactive authorization interface using the information that is optically encoded into the optical code and that the scanning device has interacted with the interactive authorization interface, wherein the indication serves as the second indicator of authorization for the processing of the transfer of the payment amount for the transaction;
• facilitating, by the at least one server of the checkout service, the processing of the transfer of the payment amount for the transaction based on the first indicator of authorization and the second indicator of authorization, and
• confirming, by the at least one server of the checkout service, that the transfer is processed.

A system for multi-factor transaction authentication utilizing a plurality of devices, the system comprising:

• one or more memory units that store instructions;
• and
• one or more processors that execute the instructions, wherein execution of the instructions by the one or more processors causes the one or more processors to:
• receive, from a browser device via an interactive purchase interface accessed via the browser device, a request to process a transfer of a payment amount for a transaction between a customer and a merchant, wherein login information associated with a login via the browser device into the interactive purchase interface serves as a first indicator of authorization for processing of the transfer of the payment amount for the transaction;
• generate an optical code that optically encodes information pointing to an interactive authorization interface, wherein the interactive authorization interface is to serve as a second indicator of authorization for the processing of the payment amount for the transaction;
• cause the optical code to be output via the interactive purchase interface of the browser device;
• receive an indication that a scanning device has used a camera of the scanning device to optically scan the optical code as displayed via the interactive purchase interface that is accessed via the browser device and that the scanning device has accessed the interactive authorization interface using the information that is optically encoded into the optical code and that the scanning device has interacted with the interactive authorization interface, wherein the indication serves as the second indicator of authorization for the processing of the transfer of the payment amount for the transaction;
• facilitate the processing of the transfer of the payment amount for the transaction based on the first indicator of authorization and the second indicator of authorization, and
• confirm that the transfer is processed.
