An example touch key system may include a master device, one or more carrier devices and protected devices, and a server. The master device may automatically detect a predefined trigger action. In response, the master device may automatically generate a carrier device credential and a corresponding cloud credential. The master device may then automatically send the cloud credential to the server. The master device may also automatically detect the carrier device in electrical communication with the master device. In response, the master device may automatically determine whether the carrier device credential from the key pair is intended for the carrier device. If so, the master device may automatically transfer the carrier device credential to the carrier device. The carrier device may use the carrier device credential to obtain access to the protected device. Other embodiments are described and claimed.
