How to unlock and trust iPhones, iPads and other iOS devices with your computer.
A lot of computer security is based on trust. Apple devices are no different.
When connecting an iPhone, iPad, or iPod to a computer for the first time, you’ll see the prompt asking you whether to trust the computer. It is designed to prevent unauthorised computers to access your devices data.
This is how you can unlock and trust your iPhone, iPad, or iPod Touch.

If asked, trust the computer.
Done!
Step 1 - Connect the device
Connect your iPhone, iPad, or iPod touch to your USB hub and then to the computer.

Step 2 - Unlock the device
Unlock your iPhone by pressing the Home button.
If you have Face ID, just tap on the screen and swipe up – the iPhone will recognise your face.
If you have Touch ID set up, the iPhone will recognise your fingerprint.
If you don’t have neither of those set up, you will need to enter your passcode.

Step 3 - Trust the computer
After a few seconds you will see a “Trust this computer?” message. Tap “Trust”.
If you have Face ID, just tap on the screen and swipe up – the iPhone will recognise your face.
If you have Touch ID set up, the iPhone will recognise your fingerprint.
On your iPhone, iPad, or iPod touch, confirm that you allow your computer or other device to access your data. If you don't want to trust the computer or other connected device, tap Don't Trust on your device. If you want to trust your computer, tap Trust.
If you are on iOS 11, your device will ask you to enter the passcode.
