To enable Stolen Device Protection on your iPhone, ensure that you meet the following requirements:

  1. Use two-factor authentication for your Apple ID.
  2. Set up a device passcode (use Face ID and Passcode for iPhones with Face ID, or Touch ID & Passcode for iPhones with Touch ID).
  3. Enable Find My.
  4. Enable Significant Locations* (a part of Location Services).

Then, turn on Stolen Device Protection:

On iOS 17.3 or later, follow these steps:

  1. Open the Settings app.
  2. Scroll down and tap on "Face ID & Passcode" (or "Touch ID & Passcode" if your iPhone has a Home button).
  3. Enter your passcode.
  4. Scroll down and tap "Stolen Device Protection."
  5. Tap "Turn On Protection."

If you can't find the Stolen Device Protection option, ensure that you have the necessary system and configuration requirements. This feature may not be available on older iPhones or if your iOS version isn't iOS 17.3 or later.
