  • an authentication server computer device including at least one computer processor operatively connected to a computer memory and configured to;

    responsive to a request to authenticate an identity of a user attempting to access the SP server via a first user device (UD), transmit a notification request to a notification server to cause the notification server to send a notification, including a token, to a second UD such that upon receipt of the notification the second UD sends data indicative of the token to the authentication server computer device, the notification server being physically distinct from the authentication server computer device;

    responsive to a failure to receive the data indicative of the token from the second UD within a timeout limit, send instructions to the first UD to make the second UD ready for communicating with the authentication server computer device;

    responsive to receiving information from the first UD indicating that the second UD is unavailable for communicating with the authentication server computer device, send instructions to the first UD such that the first UD displays instructions related to an authentication operation using a colleague UD and not including the second UD;

    initiate the authentication operation, the authentication operation including a challenge presented on the colleague UD to be completed by the user to be granted access to the SP server;
