US Patent 11528274 Accountless device control

Systems and methods for accountless device control are disclosed. For example, a smart device may be acquired and plugged in for use. The smart device may gain network connectivity and a system associated with the smart device may request enablement of an application for use with the smart device from another system, such as a system associated with a voice-enabled device. The other system may generate and send user identifier data, and the system associated with the smart device may generate a shadow account in association with the user identifier data. The application may be enabled in association with the shadow account, and access credentials may be exchanged to securely send and receive information associated with operation of the access device.
