Abstract
Disclosed embodiments relate to systems and methods for authenticating users of personal computing devices using encoded versions of the temporary and unique codes. Techniques include receiving a first cryptographic key having been created by a personal computing device and corresponding to a second cryptographic key maintained on the personal computing device; associating a user identifier with the first cryptographic key; accessing a temporary and unique code; accessing an encoded version of the temporary and unique code; making available to the personal computing device the encoded version of the temporary and unique code; receiving, from the personal computing device, a signed version of the temporary and unique code, the signed version having been signed by the second cryptographic key; verifying, using the first cryptographic key, the signed version of the temporary and unique code; and determining, based on the verifying, whether to authenticate the user of the personal computing device.
