Particular embodiments described herein provide for a wearable electronic device with a biometric sensor and logic. At least a portion of the logic is implemented in hardware. The logic is configured to receive input data indicative of biometric input and attempt to authenticate the input data based, at least in part, on at least one biometric credential of an authorized user. The logic is configured to establish a wireless connection to a smart device, determine whether the smart device is included in a trust group of one or more smart devices, and send a communication to unlock the smart device when the input data is successfully authenticated and when the trust group includes the smart device.
