Systems, methods, and computer program products for authenticating devices with device authentication identifiers

A system for authenticating devices, the system comprising:

• at least one memory storing instructions;
• at least one processor in communication with the at least one memory, the at least one processor configured to execute the instructions to:
• request first website data associated with a first website from a first merchant system;
• receive the first website data comprising a Uniform Resource Locator pointing to a second website associated with an authentication system;
• request second website data associated with the second website from the authentication system by transmitting, from the user device, a request for a device authentication identifier associated with an account of a user of the user device;
• receive the second website data from the authentication system, the second website data comprising a device authentication request message including challenge data associated with a challenge;
• generate challenge response data based on encrypting the challenge data and a unique identifier of the user device;
• transmit the challenge response data to the authentication system;
• receive the device authentication identifier in response to the authentication system authenticating a user device based on the challenge response data, the device authentication identifier uniquely identifying the user device;
• request a transaction with the first merchant system by transmitting transaction data associated with the transaction and the device authentication identifier to the first merchant system;
• generate an authorization request mess d on the transaction data and the device authentication identifier;
• transmit the authorization request message to an issuer system corresponding to an account identifier used to initiate the transaction;
• determine a device score for the user device based on the device authentication identifier;
• and
• approve or deny the transaction based at least partially on the device score.

A computer program product for authenticating devices, the computer program product comprising at least one non-transitory computer-readable medium comprising one or more instructions that, when executed by at least one processor, cause the at least one processor to:

• request first website data associated with a first website from a first merchant system;
• receive the first website data comprising a Uniform Resource Locator pointing to a second website associated with an authentication system;
• request second website data associated with the second website from the authentication system by transmitting, from the user device, a request for a device authentication identifier associated with an account of a user of the user device;
• receive the second website data from the authentication system, the second website data comprising a device authentication request message including challenge data associated with a challenge;
• generate challenge response data based on encrypting the challenge data and a unique identifier of the user device;
• transmit the challenge response data to the authentication system;
• receive the device authentication identifier in response to the authentication system authenticating a user device based on the challenge response data, the device authentication identifier uniquely identifying the user device;
• request a transaction with the first merchant system by transmitting transaction data associated with the transaction and the device authentication identifier to the first merchant system;
• generate an authorization request message based on the transaction data and the device authentication identifier;
• transmit the authorization request message to an issuer system corresponding to an account identifier used to initiate the transaction;
• determine a device score for the user device based on the device authentication identifier;
• and
• approve or deny the transaction based at least partially on the device score.
