How to disable access to the Lightning port for data transfer

The Lightning port on iOS devices is an entry point for accessing various services on iOS devices. Plugging your device into unknown USB ports for charging can be a security risk because it could potentially expose access to Photos, Contacts, and more.

To disable access to the Lightning port for data transfer, perform these steps.

  1. Open the Settings app.

  2. Navigate to Face ID/Touch ID & Passcode.

  3. Enter your passcode.

  4. Uncheck the option for USB Accessories (Figure A). This ensures that USB accessories cannot access your iOS device when it has been more than an hour since your iPhone was locked.

Turning off the USB Accessories option makes your iOS device more secure when connecting to accessories over the Lightning port.

How to set a strong passcode in iOS 13

If you are not using a passcode or are using a four-digit passcode, it’s time to upgrade your security. To do so, follow these steps.

  1. Open the Settings app.

  2. Navigate to Face ID/Touch ID & Passcode.

  3. Select Change Passcode.

  4. Enter your existing passcode.

  5. Select Passcode Options.

  6. Select 6-Digit Numeric Code or Custom Numeric Code, and enter at least six digits for the passcode (Figure B). You also have options for Custom Alphanumeric Code, Custom Numeric Code, and 4-Digit Numeric Code. Using a Custom Alphanumeric Code with uppercase and lowercase letters and special characters is the most secure option but is more difficult for you to unlock your device.

  1. Open the Settings app.

  2. Select Privacy and then disable apps in these categories that you no longer want to have access to that particular iOS service: Contacts, Bluetooth, Microphone, Speech Recognition, Camera, Health, Files And Folders, and Location Services (Figure C).
