Earlier in the month, we reported that Apple may be planning to push back against the “affordable” GrayKey iPhone unlocking boxes being sold by a former Apple employee to government authorities. While this was only hinted through iOS 11.3 and iOS 12 betas that came with a USB Restricted Mode, Apple has now confirmed this move.

The upcoming USB Restricted Mode effectively allows iOS users to limit access to a locked iPhone through its USB / Lightning port. With USB Restricted Mode enabled, users can have their iPhone’s Lightning port locked one hour after they lock their phones. If enabled – which it will be by default (yayy!) – this port can only be used for charging after that one hour period and nothing else.
