Stolen Device Protection: how to enable it on iPhone
Since iOS 17.3 — and on by default since iOS 26.4 — this setting stops a thief from using your iPhone and Apple Account. Here's how to check it, turn it on… and why it isn't enough on its own.
Your iPhone knows your passwords, your emails, your bank cards and your authentication codes. For years, a thief who had watched you type your passcode could, within minutes, change your Apple Account password, lock you out and drain your accounts. Stolen Device Protection closes that door.
Introduced with iOS 17.3 in 2024, the feature became so essential that Apple now turns it on by default on every iPhone since iOS 26.4 (February 2026). You still need to know what it does, how to set it… and understand what it doesn't protect.
The flaw it fixes
The weak link isn't your passcode: it's the moment a thief watched you type it. With your passcode and your iPhone in hand, they could once turn off “Find My,” erase every trace and resell the device. This protection stops that.
The principleWhat is Stolen Device Protection?
It's a security layer that kicks in mainly when your iPhone is away from the places you frequent (home, work). In that case, two locks are added on top of your passcode.
1. Mandatory biometrics, with no passcode fallback. For sensitive actions — viewing your saved passwords, erasing the iPhone, using a card saved in Safari — Face ID or Touch ID becomes required. There's no working around it with the passcode alone.
2. The one-hour Security Delay. For the most critical actions — changing your Apple Account password, changing the iPhone passcode, turning off “Find My” or the protection itself — the iPhone requires Face ID, then a one-hour wait, then a second Face ID. Enough time for you to mark the device as lost.
Step by stepHow to turn it on in 4 steps
Check the prerequisites
You need: two-factor authentication on your Apple Account, a device passcode, Face ID or Touch ID, “Find My” enabled, and “Significant Locations” enabled (Settings → Privacy & Security → Location Services → System Services).
Open Settings → Face ID & Passcode
Enter your passcode, scroll down to “Stolen Device Protection,” then tap the option.
Turn it on and choose the mode
Turn on the protection, then choose “Away from Familiar Locations” (active when you're out) or “Always.” For maximum security, choose “Always”: the delay will apply everywhere, even at home.
Confirm it's active
Since iOS 26.4, the option is on by default — but check anyway: an older setup may have left it off. If your iPhone runs an older version, update it first.
Physically tether your phone
Stolen Device Protection saves your data and your account — but it doesn't stop the act: your iPhone is already gone. The LOCKÜP™ bracelet links the device to your wrist with a patented magnetic lock rated at +100 lb of force. Even snatched in one pull, the phone stays with you.

Keep “Find My” and the offline network on
The protection works hand in hand with “Find My iPhone.” Also enable the offline finding network and “Send Last Location”: you'll be able to locate the device even when it's off or offline.
Back up and hide your notifications
Turn on automatic iCloud backup, and hide message previews on the Lock Screen: your authentication codes (2FA) will no longer show for everyone to see.
Software vs physicalWhat each protection really covers
Stolen Device Protection is excellent — but, like all settings, it acts after the theft. No software option stops the snatch or the drop that shatters your screen. Only a physical tether stops the act.
| Protection | Stops the theft | Protects the account | Protects the data |
|---|---|---|---|
| Passcode + biometrics | No | Partial | Yes |
| “Find My” | No | Partial | Partial |
| Stolen Device Protection | No | Yes | Yes |
| LOCKÜP™ bracelet | Yes | Yes* | Yes* |
*By stopping the theft itself, the bracelet indirectly protects your account and your data. Pair it with Stolen Device Protection for complete defense.

Frequently askedStolen Device Protection: your questions
Is the protection on by default?
Since iOS 26.4 (February 2026), yes: Apple turns it on automatically on every compatible iPhone. On an earlier version (iOS 17.3 to 18), you turn it on yourself in Settings → Face ID & Passcode.
What does the one-hour “Security Delay” mean?
For the most sensitive actions (Apple password, passcode, “Find My”), the iPhone asks for Face ID, imposes a one-hour wait, then a second Face ID. This delay keeps a thief from acting fast enough to lock you out.
“Away from Familiar Locations” or “Always”?
“Away from Familiar Locations” applies the protections away from home and work. “Always” applies them everywhere. For maximum security — or if the risk exists at home too — choose “Always.”
Does it stop my iPhone from being stolen?
No. The protection secures your data and account once the device is taken, but it doesn't stop the snatch. To prevent the physical theft, tether the phone to your wrist with a LOCKÜP™ bracelet.
What about Android?
Android offers an equivalent: “Theft Detection Lock” and remote lock, under Settings → Google → All services → Theft protection. Same idea — and the same limit: it doesn't stop the snatch.
Set up your iPhone. Then tether it.
Stolen Device Protection keeps your data. The LOCKÜP™ bracelet keeps your phone. Together, nothing slips away.
