iOS 12 boasts multiple security features including the highly effective USB Restricted Mode. So, what does this new setting do? Once activated, it prevents USB accessories from connecting to iPhone if it’s been more than one hour since the device was last unlocked. They will require your authentication to connect to the iOS device. However, you can choose to toggle ON/OFF USB accessories on your iOS 12 based on your need.
By default, USB accessories are restricted to have the access of the iPhone if it hasn’t been unlocked for more than an hour. Though it’s a great security feature, you might want to disable the USB Restricted Mode, if you regularly sync your device with iTunes.
How to Turn Off USB Restricted Mode in iOS 12 on iPhone and iPad
Step #1. Launch Settings app on your iOS device → Now, tap on Face ID/Touch ID & Passcode.
Step #2. Next, you need to enter your passcode.
Step #3. Next up, scroll down to the ALLOW ACCESS WHEN LOCKED section and turn on the switch next to USB Accessories.
Going forward, you won’t need to authenticate your locked iPhone when syncing with your computer. It can also be helpful in a situation where your device is almost dead and you want to take the help of iTunes to restore it.
That’s pretty much it!
Law enforcement officials take advantage of USB access to the iOS device to brute force a passcode using tools like GrayKey box. With the arrival of this feature, iPhone’s Lightning port data connection will no longer work with the GrayKey box beyond the limited time.
