The move will also make it more hard for police to unlock handsets without authorisation.
The tech company said the change is aimed at blocking hackers, not at hindering law enforcement agencies from doing their jobs, Reuters reported. Not just police, but identity thieves could use the Lightning port to access data. The change, which is live in the iOS 12 public beta and will reportedly be included in a "forthcoming general release", limits access to the Lightning port when a device is locked. After an hour, law enforcement won't be able to use such devices.
Apple has been at the center of such debates since it declined Federal Bureau of Investigation requests to unlock an iPhone 5C used by a gunman in the San Bernardino, California, shooting in 2015 that left 14 people dead.
Apple is reportedly closing a loophole that allows locked iPhones to be accessed without their owners' passcodes, disabling a method often used by law enforcement.
Apple will address a popular law-enforcement tool for breaking into iPhones, the company announced Wednesday.
Then-FBI Director James Comey told Congress that without compelling Apple to write new software to facilitate the digital break-in, there would be no way to learn if the shooter's device contained evidence of a conspiracy.
Apple CEO Tim Cook defended the company's decision saying, among other arguments, that weakening encryption gives criminals and other malicious actors an easier way to break into phones. The USB 3.1 standard powering most new USB-C devices offers as much as 10 Gbps in data transfer rates and is capable of providing up to 100 W of power.
Until recently, current FBI Director Christopher Wray repeatedly claimed that the Bureau had been unable to get into more than 7,000 phones in 2017.
