Stolen Device Protection reduces the damage a thief can do if they steal your iPhone and also know your passcode. For sensitive account changes away from familiar locations, the iPhone requires Face ID or Touch ID instead of letting the passcode act as a fallback.
Does this affect you?
Use this for iPhones on iOS 17.3 or later with Face ID or Touch ID, a device passcode, Find My, and two-factor authentication on the Apple Account. On newer iOS releases, the feature may already be enabled, so the steps below also help you confirm it.
Turn on Stolen Device Protection
Once the requirements are met, the setting is quick to check.
- Open Settings.
- Tap Face ID & Passcode or Touch ID & Passcode, depending on the iPhone model.
- Enter the iPhone passcode.
- Scroll to Stolen Device Protection.
- If it already shows as on, leave it enabled.
- If it is off, tap Turn On Protection.
Daily iPhone use should feel mostly the same. The feature changes what is required for specific sensitive actions, especially when the phone is away from familiar places such as home or work.
Fix it if the option is missing or grayed out
Stolen Device Protection depends on several Apple security settings.
- Confirm two-factor authentication is on under Settings > your name > Sign-In & Security.
- Turn on Significant Locations under Settings > Privacy & Security > Location Services > System Services. On some versions it may be labeled Significant Locations & Routes.
- Confirm Find My iPhone is enabled under Settings > your name > Find My > Find My iPhone.
- Return to Settings > Face ID & Passcode > Stolen Device Protection and try again.
More control
What changes when you are away from familiar locations
Actions such as viewing saved passwords or using saved Safari payment details can require biometric authentication with no passcode fallback. Higher-risk changes, including changing the Apple Account password, disabling Find My, adding Face ID, or turning off Stolen Device Protection, may require a security delay and a second biometric check.
Why familiar locations matter
At places your iPhone recognizes as routine, the phone behaves more normally. The stricter flow appears when the device is somewhere unfamiliar, which is the situation that matters most after theft.
Still strengthen the passcode
Use a longer passcode and avoid entering it where someone nearby can watch. Stolen Device Protection is an added layer, not a reason to treat the passcode casually.
