Devices, systems, and methods for storing and managing sensitive information in a connected environment are provided. The system comprises a master controller and a sensitive information storage device (“SIS device”). The SIS device has an island that can be activated by user interaction with the SIS device. In general, the island is deactivated by default and when the island is deactivated, sensitive information that is stored on the SIS device cannot be accessed. Only when the island is activated by user interaction can the stored sensitive information be accessed.
