Systems, methods, and apparatuses for location-based automated authentication are disclosed. A system comprises a mobile device, a sensor and a backend platform. The sensor and the backend platform are in network communication. The mobile device is operable to continuously transmit Bluetooth Low Energy (BLE) signals comprising encrypted transitory identifiers. The sensor is operable to receive a BLE signal from the mobile device when the mobile device is within a predetermined range, and communicate over a network connection the encrypted transitory identifier comprised in the BLE signal to the backend platform. The backend platform is operable to extract a unique identifier and a changing encrypted identifier from the received encrypted transitory identifier, generate a changing encrypted identifier, and validate a user identification by comparing the generated changing encrypted identifier and the extracted changing encrypted identifier.
