Systems and techniques for configuring wireless devices are described. To configure a wireless target device to access a network and/or network-based services, a wireless connection may be formed between the wireless target device and a wireless source device storing configuration data for accessing one or more networks and/or network-based services. The source device may determine whether it is authorized to send at least a portion of the configuration data to the target device. The target device may determine whether it is authorized to accept at least a portion of the configuration data provided by the source device. The target device may accept at least a portion of the configuration data by storing the accepted configuration data in a memory (e.g., a non-volatile memory) and/or by using the configuration data to access a wireless network and/or a network-based service.
