I've forgotten my iPhone 7 passcode and can't unlock it. So, I tried to restore it to the factory settings with iTunes. But when I connect my iPhone to my computer, it says "Unlock iPhone to use accessories", and it's not picked up by the computer. Is there anything I can do? Any advice on how to get round this problem would be very much appreciated. Thank you!

So, you've noticed that a message "Unlock iPhone to use accessories" is preventing your locked iPhone from connecting to your computer? This is because of the USB Accessories Restricted Mode, a new security feature Apple added in iOS 11.4.1 and later to protect iPhone from unauthorized access by USB connections. This feature enhances iPhone security, but in some cases, you may find it annoying and want to disable it, especially if you forgot your iPhone passcode and can't unlock your device. So, on this page, we will show you how to solve "Unlock iPhone to use accessories" if you forgot your passcode.


Part 1: Fix "Unlock iPhone to use accessories" without passcode

Part 2: How to disable "Unlock iPhone to use accessories" message

In iOS 11.4.1 and later, the USB Accessories restricted mode is enabled by default on a passcode-protected iPhone, and it's not recommended to disable it from a security perspective. But, if this feature is really annoying you, you can turn it off.

Step 1: Unlock your iPhone and open the Settings app.

Step 2: Go to Touch ID & Passcode (or Face ID & Passcode).

Step 3: Enter your iPhone passcode to proceed.

Step 4: Locate the USB Accessories option and toggle it ON. Having this option turned on means that USB Accessory Restricted Mode is disabled. That is to say, USB accessories are always allowed to be connected when the iPhone is locked. You will no longer see the "Unlock iPhone to use accessories" message when you connect the locked iPhone to a computer or USB accessory.
