A pair of remote computing devices for authenticating a user of one of the pair of remote computing devices, the pair of remote computing devices consisting of a first computing device comprising a first processor and a first memory, the first computing device configured to communicate with a host computing device, and the first memory stores sample biometric data associated with the user of the first computing device; and a second computing device comprising a second processor and a second memory, the second computing device configured to automatically receive and transmit messages with the first computing device; the first computing device configured to: receive, from the host computing device, an authentication request message for authenticating the user of the first computing device; process the authentication request message; transmit a biometric request message to the second computing device in response to receiving the authentication request message; receive captured biometric data from the second computing device, the captured biometric data being captured by the second computing device; electronically compare the captured biometric data to the sample biometric data stored within the first memory; and transmit an authentication response message to the host computing device based upon the comparison of the captured biometric data to the sample biometric data, the authentication response message indicating whether the captured biometric data matched the sample biometric data; wherein the second computing device comprises a plurality of second computing devices within a predetermined radius of the first computing device, and wherein the first computing device is further configured to: determine a type of biometric data requested based on the received authentication request message; detect the type of biometric data each of the plurality of second computing devices is configured to capture; and transmit the biometric request message to one of the second computing devices in response to determining that the second computing device is configured to capture the requested biometric data. a first computing device comprising a first processor and a first memory, the first computing device configured to communicate with a host computing device, and the first memory stores sample biometric data associated with the user of the first computing device;
