1. An authentication server, comprising:
one or more processors; and
one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the authentication server to perform operations comprising:
receiving user information associated with a first authentication factor for verification from a first endpoint device;
in response to verifying the first authentication factor, transmitting a prompt to provide an authentication decision associated with a second authentication factor to a second endpoint device, wherein:
the second endpoint device is communicatively coupled to the first endpoint device through a communication link,
the second endpoint device is registered to communicate with the authentication server and the first endpoint device is not,
the first endpoint device and the second endpoint device are associated with a user,
a first instance of an authentication application is installed on the first endpoint device to facilitate communication with the authentication server; and
a second instance of the authentication application is installed on the second endpoint device to facilitate communication with the authentication server; and
receiving the authentication decision that is initiated by the first endpoint device from the second endpoint device, wherein the first endpoint device is configured to initiate and transmit the authentication decision to the second endpoint device in response to receiving the second authentication factor from the second endpoint device.
