Part 1. Why Does 'Unlock iPhone to Use Accessories' Prompt on My iPhone

It' s a common phenomenon that 'unlock iPhone to use accessories' appears on your iPhone. This is an important privacy protection measure that Apple has added to iOS devices since iOS 11.4.1, usually called 'USB restricted mode'. If you haven't unlocked your iOS device with a passcode first, or if you haven't unlocked it and connected it to a USB accessory in the past hour, your iOS device won't be connected to the accessory or your computer. Additionally, it can also be used to prove that the accessory you're using to charge is original. So, when connecting some accessories, you need to unlock your iPhone to ensure that only authorized accessories are able to communicate with the device.
