I guess it depends what &quot;security&quot; we&#x27;re discussing.<p>I was talking about passive signal noise which could be used to locate a potential target (e.g. pick the president&#x27;s vehicle from the identical ones in the motorcade). Even a hardened phone will still leak EM radiation.<p>If we&#x27;re talking about informational security, well, I don&#x27;t know why we would. The Fitbit doesn&#x27;t sync realtime and most of the president&#x27;s meetings are public. So while it would be extremely embarrassing, I don&#x27;t know how compromising it would be.
