Apple puts a lot emphasis on the protection of privacy. With each update, they make their iOS system more secure. But these new protections, in some cases, can cause some annoying problems.

One of the most common problems appears since Apple updated their iOS 12. If you connect your iPhone to your Windows computer or Mac, chances are that you will see the message "Unlock iPhone to use accessories". There is no need to worry, however, as this article is a full guide on how to fix the unlock iPhone to use accessories issue.

Part 1. Everything About "Unlock iPhone to Use Accessories"

As I mentioned before, to save users from hackers, Apple keeps preparing its countermeasures, and this message is related to it. You will not see this issue on iOS 11 or earlier because it is due to the USB Restriction Mode, which will further evolve in the next updates, i.e. iOS 12 or later.

What Does the Message Mean?

This message means that you can not connect your iPhone to the computer or MAC device unless you unlock it. Although this can be very helpful in terms of protection and security, on the other hand, it can be inconvenient and annoying.

For example, when you frequently transfer files, music, and other data from or into the iPhone, you have to unlock it every time you connect it again. This is not a big deal once or twice, but sometimes we rush, and these extra steps annoy us.

In What Cases Would This Message Appear?

You will see this message when the USB accessories is disabled, which makes it necessary for you to unlock the iPhone to connect it to the computer. Because of this mechanism, you are protected from unauthorized access.

Let us explain why this is important. These days the fastest way to get someone's data or other sensitive information is through his smartphone. And the fastest way to transfer the data or install something harmful on the device is through the USB data transfer, which is exactly what many hackers do.

To patch the security threads, therefore, Apple came up with the idea that prohibited an unauthorized person from connecting the device to computer via USB at the very first beginning.

Part 2. Fix "Unlock iPhone to Use Accessories" With Passcode

You can turn off this option if you want to, but this may bring some safety risks. Still, if this problem is irritating or you want to fix this issue temporarily until you finish transferring your data, follow these simple steps.

  • Step 1. Go to Settings > Face ID & Passcode or Touch ID & Passcode.
  • Face ID & Passcode
  • Step 2. When asked for the screen passcode, enter it to proceed.
