Unlock iPhone to use accessories” is an error message related to devices that run on iOS.

This message may appear when you connect your iPhone to a Mac or a PC through a USB cable.

This error is not just related to iPhones, but it can be seen on iPads as well. This guide will explain how to fix this error with easy methods.

What Does It Mean by “Unlock iPhone to Use Accessories”?

The error “unlock iPhone to use accessories” appears because of a specific security feature integrated into Apple devices. This feature is introduced to prevent unauthorized access.

Though it sounds like a very impressive thing, it can also become a pretty annoying feature as well. When you need to connect your iOS device quickly to a computer, this feature can be a burden.

If we are to explain this more, this error message appears because of the USB restricted mode. This feature was added to iOS devices with their iOS 11 version. From that point onwards, this USB restriction feature appeared in all the iOS versions.

This restriction prevents your iOS device from connecting with a computer when it is locked. But the devices connected using lightning ports can be changed without transferring any sort of data.

If you want to access the device through the computer or share any data, it must be authorized. That means it demands you to unlock the device to connect the device with a computer and share data.

Why Did Apple Introduce This Feature?

Many individuals wonder why this specific feature is introduced to iOS. Well, the answer is straightforward. It is all about the security of your data. Thanks to the advancements in the latest technology, a large range of threats pertaining to security have emerged.

With the restriction feature introduced by Apple, your iOS device will not be able to connect to any computer. To connect, you should unlock the device using the device’s passcode, Touch ID, Face ID, etc.

As long as the device is locked, you will see the “Unlock iPhone to use accessories” message.

So, in a nutshell, the “unlock iPhone to use accessories” message appears due to a security feature.

Besides, are you receiving the warning message on your iPhone stating “liquid detected in lightning connector“? If that’s the case, let’s fix it simply.

How to Get Rid of the Unlock iPhone to Use Accessories Message?

Disabling this security feature is not the most intelligent decision you should take. All you need is to unlock the device whenever you need to connect it to a computer through USB. So, we always recommend you to have this feature.

However, if You Still Want to Disable It, Mentioned Below Are Instructions You Should Follow.

  • First, you should open “Settings” on your device.
  • Once you have done that, tap on the option labeled “Touch ID & Passcode” (or “Face ID & Passcode”).
  • When you are on that screen, you will be able to see an option called “USB Accessories.” It is located at the bottom of the screen labeled “Allow Access When Locked.”

  • Now, you should turn on the option called “USB Accessories.” Turning on this option will disable the restricted mode on your iPhone.
  • After that, your device can be connected to any computer, whether it is locked. However, this is a pretty risky approach in terms of data security.

What we strongly suggest is that you keep the restriction on to prevent potential data theft. Also, if you have already turned it off, we strongly recommend you turn it on after using it.

What you should understand is that “unlock iPhone to use accessories” is not necessarily an error. In fact, it is a warning message or an alert saying that your device has a restriction. It surely prevents your device from communicating with the computer through a USB cable.

But, as mentioned before, it becomes more annoying when you need to connect a device immediately. That is exactly why individuals want to prevent this message from appearing upon connecting to a computer.

As mentioned before, preventing this message from popping up is not difficult at all. As long as you have the passcode, you can easily enter it and unlock the device.

After unlocking the device, the respective message will go away. Also, the connected peripheral or the computer will communicate with the device without any disturbance.
