Remarks
Explicitly set the storage location used internally by this class to be device-protected storage.
On devices with direct boot, data stored in this location is encrypted with a key tied to the physical device, and it can be accessed immediately after the device has booted successfully, both <em>before and after</em> the user has authenticated with their credentials (such as a lock pattern or PIN).
Because device-protected data is available without user authentication, you should carefully limit the data you store using this Context. For example, storing sensitive authentication tokens or passwords in the device-protected area is strongly discouraged.
