Turn on Stolen Device Protection on iPhone Duo

iPhoneUpdated

Stolen Device Protection works on iPhone Duo the same way it does on any iPhone with iOS 17.3 or later. The one difference is the biometric: on iPhone Duo every check it asks for is Touch ID, because Apple says iPhone Duo uses Touch ID and has no Face ID. Turn it on in Settings > Touch ID & Passcode.

Quick answer

Go to Settings > Touch ID & Passcode, enter your passcode, tap Stolen Device Protection and turn it on. You need two-factor authentication, a passcode, Touch ID, Significant Locations and Find My. Away from familiar places, some actions then need Touch ID with no passcode fallback, and some need a one-hour delay.

What does Stolen Device Protection do on iPhone Duo?

Apple says it helps prevent someone who has stolen your iPhone and knows your passcode from making critical changes to your account or device. It does that in two ways when the phone is away from familiar locations such as home or work.

  • Biometric only. Some actions need Face ID or Touch ID, with no passcode alternative. On iPhone Duo that's Touch ID.
  • Security Delay. Some changes need Touch ID, a one-hour wait, then Touch ID again.

Apple describes the delay as there to stop a thief performing critical operations, so you have time to mark the phone as lost and secure your Apple Account.

Nothing about this is specific to iPhone Duo. Apple's article covers every iPhone. It matters on iPhone Duo because, as Apple says, Touch ID is the only biometric the phone has.

How do you turn on Stolen Device Protection on iPhone Duo?

Apple says it must be turned on before the phone is lost or stolen, and that it may already be on by default. Check now.

  1. Go to Settings > Touch ID & Passcode.
  2. Enter your passcode.
  3. Tap Stolen Device Protection and turn it on.

Apple's article writes the first step as Face ID & Passcode. On a Touch ID model such as iPhone Duo, Apple's iPhone User Guide uses Settings > Touch ID & Passcode.

What do you need first?

Apple lists five things:

  1. Two-factor authentication for your Apple Account: Settings > [your name] > Sign-In & Security.
  2. A device passcode.
  3. Touch ID.
  4. Significant Locations: Settings > Privacy & Security > Location Services > System Services > Significant Locations & Routes.
  5. Find My, which you can't turn off while Stolen Device Protection is on.

Set up a new iPhone Duo securely covers all five in order.

Which actions need Touch ID with no passcode fallback?

Away from familiar locations, Apple lists these:

  1. Using passwords or passkeys saved in Keychain.
  2. Using payment methods saved in Safari AutoFill.
  3. Turning off Lost Mode.
  4. Opening a locked app.
  5. Erasing all content and settings.
  6. Applying for a new Apple Card, or viewing your Apple Card or Apple Cash virtual card number.
  7. Certain Apple Cash and Savings actions in Wallet.
  8. Using your iPhone to set up a new device, for example with Quick Start.
  9. Setting up or transferring an eSIM.

That last one matters on iPhone Duo. Apple says the phone is eSIM only, so any eSIM change made away from home will ask for your fingerprint.

Apple notes you can still use your passcode for Apple Pay purchases.

Which changes need the one-hour Security Delay?

Away from familiar locations, Apple says you authenticate with Touch ID, wait for the delay to end, then authenticate again to:

  1. Change your Apple Account password.
  2. Sign out of your Apple Account.
  3. Update Apple Account security settings, such as trusted devices, a Recovery Key or a Recovery Contact.
  4. Add or remove Face ID or Touch ID.
  5. Change your passcode.
  6. Reset All Settings.
  7. Enrol in Mobile Device Management.
  8. Turn off Stolen Device Protection.

Apple says the phone may end the delay early when it detects you've arrived at a familiar location. You also can't change these settings on the web at account.apple.com while the protection is on.

Should you choose Always?

It's worth considering. By default the extra steps apply only away from familiar locations, which Apple says typically include your home, work and other places you regularly use your phone. If you'd like them everywhere:

  1. Go to Settings > Touch ID & Passcode.
  2. Tap Stolen Device Protection.
  3. Under Require Security Delay, choose Always.

Apple says that with Always on, security changes will always need a delay and biometric actions will always need Touch ID, even at home.

Does it carry over from your old iPhone?

Yes. Apple says that when you restore from iCloud Backup or transfer directly from a previous iPhone, Stolen Device Protection is restored too, and resumes automatically. There may be a delay before the new phone recognises your familiar locations.

Turn it off on the old phone before you sell, give away or trade it in. Apple says that if you try to turn it off away from a familiar location, the security delay starts first.

What if your iPhone Duo is stolen?

Mark it as lost straight away from another device or at icloud.com/find. With Stolen Device Protection on, Apple says turning off Lost Mode needs Touch ID, so knowing your passcode isn't enough to undo it. The full steps are in iPhone Duo stolen: what to do and phone stolen with the passcode.

Apple adds that if you change your Apple Account password on your iPhone with the protection on, the location of your devices may not be visible at iCloud.com for a while.

Where Failshot fits

Apple built Stolen Device Protection for a thief who already knows your passcode. Your passcode is the first layer. Failshot is the second.

Failshot for iPhone is coming soon. When it's out, you'll turn it on, leave Failshot open on its own screen and lock your iPhone, and whoever unlocks it into Failshot will be photographed. Get early access and we'll email you when Failshot for iPhone is ready.

Failshot for Mac is out now, for macOS 14 or later.

More questions

Is Stolen Device Protection on by default on iPhone Duo?

Apple says it may be on by default, without saying so for any model in particular. Check in Settings > Touch ID & Passcode > Stolen Device Protection. If you restored from an old iPhone that had it on, Apple says the setting comes across.

Does Stolen Device Protection work without Face ID?

Yes. Apple's article says Face ID or Touch ID throughout. iPhone Duo uses Touch ID, so every biometric check Stolen Device Protection asks for on iPhone Duo is a fingerprint on the side button.

What if Touch ID isn't working and I need it for Stolen Device Protection?

Away from familiar places, some actions have no passcode fallback, so a working sensor matters. Work through Apple's steps in Touch ID not working on iPhone Duo, or wait until you're somewhere familiar, where Apple says your passcode works as normal.

Can I turn off Stolen Device Protection quickly?

Not away from familiar locations. Apple lists turning it off among the changes that need Touch ID, a one-hour security delay, then Touch ID again. At a familiar location, with Always not chosen, Apple says the extra steps aren't required.

Which iOS version does Stolen Device Protection need?

iOS 17.3 or later, according to Apple. Apple's announcement says iPhone Duo comes with iOS 27.1, so every iPhone Duo has it available.
