About the 'Trust This Computer' alert on your iPhone, iPad, or iPod touch

Learn about trusted computers and find out how to change your settings.

What the trust settings on your device mean

When you connect your iPhone, iPad, or iPod touch to a computer or other device for the first time, an alert asks whether you trust the computer:

  • Trusted computers can sync with your device, create backups, and access your device's photos, videos, contacts, and other content. These computers remain trusted unless you change which computers you trust or erase your device.
  • If you choose not to trust a computer, you block its access to content on your device. The trust alert appears every time that you connect your device to that computer.

Choose whether to trust a computer

  1. Connect your iPhone, iPad, or iPod touch to your computer or another device.
  2. Enter your passcode, if you have one, to unlock your iPhone, Pad, or iPod touch.
  3. If you want to allow your computer to access information on your device, select your device in the Finder and click Trust, or if you're using iTunes, click Continue.

  4. 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.

Change your settings for trusted computers

Your device remembers the computers you've chosen to trust.

If you don't want to trust a computer or other device anymore, reset the Location & Privacy settings on your iPhone, iPad, or iPod touch. Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Location & Privacy. Now when you connect to formerly trusted computers, the Trust alert will ask you whether you trust that computer. 

Get help

If you tap Trust or Don't Trust, but your computer doesn't accept your answer, or if the Trust alert won't appear, follow these steps. Try again after each:

  1. Make sure that your computer has the latest version of macOS or the latest version of iTunes
  2. Disconnect and reconnect your device from your computer.
  3. Restart your computer.
  4. Restart your device:
  5. Reset your Location & Privacy settings.

If the above steps don't help, go to Settings > General > Transfer or Reset [Device] > Reset and tap Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

If you downloaded iTunes for Windows from the Microsoft Store, make sure that iTunes Mobile Device Helper is enabled as a startup item.
