Aspects of the disclosure relate to authorizing an event by utilizing a high generation cellular network to authenticate a device associated with the event. A computing platform may receive, from a first device, a request to authorize an event. Subsequently, the computing platform may identify, based on an analysis of location data, that a second device is proximate to the first device. The computing platform may then prompt the second device to authenticate the first device. Then, the computing platform may receive, from the second device, an authentication token indicating whether the first device is authenticated. Based on the authentication token, the computing platform may respond to the request to authorize the event.
