Abstract
An apparatus and method are described for sharing WiFi credentials. For example, one embodiment of a method comprises: generating a first secret on a first IoT device, the first IoT device having WiFi credentials stored thereon; sharing the first secret with a second IoT device; encrypting the WiFi credentials on the first IoT device using the first secret to generate encrypted WiFi credentials; receiving the encrypted WiFi credentials from the first IoT device at an IoT service; encrypting the encrypted WiFi credentials at the IoT service using a second secret to generate twice-encrypted WiFi credentials, the second secret known by the second IoT device; transmitting the twice-encrypted WiFi credentials from the IoT service to the second IoT device; decrypting, at the second IoT device, the twice-encrypted WiFi credentials using the second secret to generate the encrypted WiFi credentials and decrypting the encrypted WiFi credentials using the first secret to generate the WiFi credentials; and establishing a secure WiFi connection on the second IoT device using the WiFi credentials.
