Stolen Device Protection is an iPhone setting that stops a thief who knows your passcode from taking over your Apple Account. With it on, the most damaging changes need your face or fingerprint, and some also need a one-hour wait. It takes one minute to turn on.
Checked on 30 October 2026.
Why does a passcode alone put you at risk?
A thief who watches you type your iPhone passcode in a bar or on a train can, within minutes, change your Apple Account password, turn off Find My and open your saved passwords. Without Stolen Device Protection, the passcode unlocks all of it.
What do you need before you turn it on?
Stolen Device Protection needs iOS 17.3 or later, a passcode, Face ID or Touch ID, two-factor authentication on your Apple Account, and Find My iPhone turned on in Settings > [your name] > Find My.
How do you turn on Stolen Device Protection?
When does the security delay apply?
Under Require Security Delay, iPhone offers two choices. Away from Significant Locations applies the extra checks only when the iPhone is away from places it knows, such as home or work. Always applies them everywhere, including at home.
What changes when Stolen Device Protection is on?
When the iPhone is away from familiar places:
The one-hour wait gives you time to mark the iPhone as lost at icloud.com/find from another device.
Is Stolen Device Protection enough on its own?
No. Stolen Device Protection is a second line of defence. Use a passcode of six digits or more, and cover the screen when you type it in public.
What does a VPN change, and what does it not?
A VPN encrypts the connection between your phone and the VPN server, so the Wi-Fi network and your internet provider cannot see which sites and apps you talk to. A VPN cannot stop someone who holds your unlocked iPhone. Stolen Device Protection and a strong passcode cover that risk. More on the limits: What a VPN cannot protect you from.
Frequently asked questions
Does Stolen Device Protection slow down everyday use?
No. At home or work, with the default setting, the iPhone works as before. The extra checks only start away from familiar places.
What if Face ID fails while I am away from home?
Protected actions such as opening saved passwords wait until Face ID or Touch ID succeeds. The passcode is not accepted instead.
Can I turn Stolen Device Protection off later?
Yes, in the same menu. Away from familiar places, turning it off needs Face ID and the one-hour wait.
