Systems and methods for device to device authentication

An authentication computing device for authenticating a user device, said authentication computing device comprising one or more processors in communication with one or more memory devices, said authentication computing device configured to:

• generate a locked data file for use in authenticating a user device enrolled in an authentication service, the locked data file is configured to process a challenge and generate a challenge response;
• transmit the locked data file to a first user device as part of the first user device enrolling in the authentication service;
• receive an authentication request;
• generate the challenge based on the authentication request;
• transmit the challenge from said authentication computing device to the first user device;
• and
• receive the challenge response from the first user device to authenticate the first user device.

A computer-readable storage medium having computer-executable instructions embodied thereon, wherein when executed by an authentication computing device having one or more processors in communication with one or more memory devices, the computer-executable instructions cause the authentication computing device to:

• generate a locked data file for use in authenticating a user device enrolled in an authentication service, wherein the locked data file is configured to process a challenge and generate a challenge response;
• transmit the locked data file to a first user device as part of the first user device enrolling in the authentication service;
• receive an authentication request;
• generate the challenge based on the authentication request;
• transmit the challenge from the authentication computing device to the first user device;
• and
• receive the challenge response from the first user device to authenticate the first user device.
