    1

    Make sure you have iOS 17.3 or later

    ~15s
    Go to SettingsGeneralAbout → iOS Version. If it shows 17.3 or higher (including iOS 18.x), you have the right version. If not, go to SettingsGeneralSoftware Update and update your iPhone first.
    2

    Turn on Stolen Device Protection

    ~21s
    Go to SettingsFace ID & Passcode (or Touch ID & Passcode). Enter your passcode. Scroll down to find "Stolen Device Protection." Tap "Turn On Protection." That is all — it is now active.

    Quick Tip

    Quick Tip: This setting is easy to miss because it is buried in the Face ID settings. Do this now while it is on your mind.

    3

    Understand what it protects

    ~20s
    With the feature on, these actions now require Face ID or Touch ID — no passcode fallback: changing your Apple ID password, turning off Find My iPhone, turning off Stolen Device Protection itself, adding or removing Face ID/Touch ID, and applying for a new Apple Card. In an unfamiliar location, some of these also trigger a one-hour security delay.
    4

    Set your security delay preference

    ~17s
    Tap "Security Delay" under the Stolen Device Protection section. You can choose "Always" (the delay applies even at home) or "Away From Familiar Locations" (delay only applies when you are not at home or work). Most people choose "Away From Familiar Locations" so daily use at home is not affected.
    5

    What to do if your phone is stolen

    ~30s
    Right away log in to iCloud.com from any computer or another phone. Click "Find My" → select your iPhone → "Lost Mode" to lock it and display a message with your contact number. If you cannot recover it, use "Erase iPhone." With Stolen Device Protection on, the thief is locked out of making account changes during this window.

    Warning

    If you trade in or sell your iPhone, turn off Stolen Device Protection first, then sign out of your Apple ID, then factory reset. This prevents issues during the trade-in process.

    Stolen Device Protection is a security feature Apple added to iPhones with iOS 17.3 and later. It protects you from a specific type of theft that became common: thieves watch you enter your passcode in public, then steal your phone. Within minutes, they can change your Apple ID password, turn off Find My iPhone, and lock you out of your own account permanently.

    With Stolen Device Protection turned on, this attack no longer works. The feature requires Face ID or Touch ID (biometric authentication) for sensitive actions. There is no fallback to a passcode. Also, some of the most dangerous actions (like changing your Apple ID password or turning off Find My iPhone) have a built-in one-hour delay when your phone is in an unfamiliar location.

    This means even if a thief has your passcode, they cannot instantly take over your account. The delay gives you time to log in from another device and remotely lock or wipe the stolen phone before the thief completes their attack.

    Stolen Device Protection is turned off by default. You have to enable it manually. It works on iPhone XR, XS, and all newer models running iOS 17.3 or later.
