1. A method of authenticating a user who requests an access to a device, the method comprising the steps of:

  • receiving, by a hardware processor of the device, a request to authenticate the user who is requesting the access to the device;

    in response to the step of receiving the request to authenticate, polling, by the processor, for historical data that includes (1) social media interactions that specify a person authorized to access the device and (2) geolocations of the person;

    automatically generating, by the processor, a question that is relevant to a social media interaction included in the social media interactions, a geolocation included in the geolocations, or a combination of the social media interaction and the geolocation of the person authorized to access the device;

    receiving, by the processor, a digital representation of a voice that provided an answer to the question, the digital representation of the voice being generated and stored in an audio file format by a digital audio technology coupled to the hardware processor, and the voice being spoken by the user who is requesting access to the device;

    based on the received digital representation of the voice that provided the answer, verifying, by the processor, that the voice that provided the answer matches a voice of the person authorized to access the device;

    determining, by the processor, that the answer to the question is correct;

    based on (1) the voice that provided the answer matching the voice of the person authorized to access the device and (2) the answer being correct, authenticating, by the processor of the device, the user and granting to the authenticated user the access to the device;

    receiving, by the processor, a first period of time during which a first portion of the historical data that includes the geolocations is collected; and

    receiving, by the processor, a second period of time during which a second portion of the historical data that includes the social media interactions is collected,wherein the step of polling for the historical data includes polling first data indicating geolocations whose timestamps indicate locations of the person authorized to access the device within the first time period and polling second data indicating social media interactions whose timestamps indicate interactions within the second time period.
