Disclosed embodiments relate to systems and methods for dynamically providing coupling between auxiliary computing devices and secure endpoint computing resources. Techniques include identifying a request for an identity to access an endpoint computing resource; obtaining a unique session identifier in response to the request; transmitting the unique session identifier via short-range communications from the endpoint computing resource to an auxiliary computing device associated with the identity; obtaining, in response to the auxiliary computing device transmitting the unique session identifier and the identification data, authentication data sufficient to comply with the authentication requirement of the endpoint computing resource; and dynamically coupling the identity to the endpoint computing resource based on the authentication data and consistent with the authentication requirement.
