Managing Trusted User Devices Via Silent Push Notifications

Methods, systems, and apparatuses for managing the preauthorization of user devices to access resources in one or more remote servers are described herein. Preauthorized user devices may access the resources without repeatedly going through multiple-factor authentication processes. Data for such preauthorized user devices may be maintained in a list of trusted user devices. To determine whether user devices are still eligible to be included in the list of trusted user devices, silent push notifications may be sent to the user devices. The silent push notifications may be configured not to cause outputs of any displays at the user devices or modify any current displays. Based on deliverability statistics that indicate whether the user devices acknowledged the silent push notifications, user devices may be kept in the list of trusted devices or removed from the list of trusted devices.
