implementing a platform and language agnostic one authorization application module (OAAM) configured to allow an authenticated user to access a plurality of resources by a single authentication, the OAAM including an accessing module, generating module, reading module, authenticating module, and a configuring module, wherein each module being called via a corresponding Application Programming Interface (API);

accessing an application within a user computing device, the application being configured to authenticate a user based on a facial recognition protocol by calling the accessing module via a first API;

successfully logging in, via the OAAM, the user into the application based on a positive facial recognition result for gaining access to a building;

generating, in response to successful login, a quick response code and a near field communication tag by calling the generating module via a second API;

transmitting the quick response code and the near field communication tag to the user computing device by calling the generating module via the second API;

reading the quick response code or the near field communication tag by a security system installed in an entry point to the building in response to bringing the user computing device close to the security system by calling the reading module via a third API;

authenticating the user based on successful reading of the quick response code or the near field communication tag by calling the authenticating module via a fourth API; and

configuring the quick response code or the near field communication tag as a single authentication pass allowing the user to enter the building and access the plurality of resources for a predetermined configurable period by calling the configuring module via a fifth API.
