1. A method for authenticating a user device by an authentication computing device, the method comprising:

  • generating, using the authentication computing device, a locked data file for use in authenticating a user device enrolled in an authentication service, the locked data file configured to process a challenge and generate a challenge response;

    transmitting the locked data file from the authentication computing device to a first user device as part of the first user device enrolling in the authentication service, causing the locked data file to be installed on the first user device;

    receiving, at the authentication computing device, an authentication request for a transaction initiated using the first user device;

    generating, using the authentication computing device, the challenge based on the authentication request;

    transmitting the challenge directly from the authentication computing device to the first user device, wherein the challenge requests a current activated lifetime of the locked data file, and wherein the current activated lifetime is a time difference between a first time when the first user device receives the locked data file and a second time when the first user device receives the challenge; and

    receiving, at the authentication computing device, the challenge response directly from the first user device to authenticate the first user device, wherein the challenge response includes the current activated lifetime.
