The device identifier is used to generate a device key that will uniquely identify the particular computing device. The computing device stores the device key in a data store, and sends the device key to be stored on a first computer server. The computing device subsequently requests a user action from a second computer server, and the second computing server requests user authentication. The computing device generates a first authentication code using a cryptographic hash algorithm and the device key, and sends the first authentication code to the second computer server. The computing device is authenticated based on a second authentication code generated by the first computer server using the device key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Providing user authentication","description":"In particular embodiments, a computing device accesses a device identifier that is encoded in the hardware of the computing device.
