Audio components such as headsets or earbuds can include a control module that stores an identifying code. When an audio component is connected to an electronic device, the device determines the code and can set certain parameters (e.g., audio playback volume) and/or provide at least some level of access to functionality and data. The control module also includes one or more buttons that enable a user to provide an input sequence that can act as a personal code. When the electronic device receives the personal code and verifies that the code is associated with the identifying code of the audio component, the electronic device can provide access to additional and/or all functionality on the device, and any or all data stored for the user or device. The sequence can correspond to a beat pattern or musical sequence entered using the buttons.
