Abstract
In an embodiment, a set of dynamic proximity attribute (DPA) Risk Signals (RS) indicating whether a user is within a predetermined proximity of a registered user mobile device (RUMD) and a registered user device (RUD) is received from the RUMD and at an identity provider (IDP) communicably coupled to the RUMD based on short-range communication between the RUMD and the RUD. The RUMD is configured to monitor devices in short-range communication in a dynamic proximity area network (DPxAN) via an IDP application (IDPAmd) associated with the RUMD. A Risk Parameter Value (RPV) is determined according to at least the set of DPA RS received from the RUMD. A passwordless request to authenticate the user at the RUD on which a user access request originated is received from a Service Provider (SPn) by the IDP. An authentication response is sent from the IDP to the SPn based on the RPV.
