Embodiments described herein provide a security model and interface for wearable device digital purchases that can be made without the assistance of a companion device. The satellite device can be configured to be used as a primary device, without reliance upon a paired device. A provisioning process may be implemented to generate and validate one or more tokens to authenticate the wearable device and a set of cryptographic keys can be generated. Subsequently, the token(s) and cryptographic keys may be used to enable a user of the wearable device to make purchases from a digital shopping store without support from an associated companion electronic device.
