How to set up Find My iPhone

Find My iPhone is built into every iPhone and iPad. To turn it on, open Settings, tap your name at the top, select iCloud, then tap Find My. Toggle on Find My iPhone. That's the setup — it takes about 30 seconds and requires your Apple ID password to confirm.

Find My iPhone works by connecting to Apple's servers using your Apple ID. When you turn it on, your device location is encrypted and stored so you can find it later from another device or from iCloud.com. The feature works even if your phone is locked, offline, or powered down — though a powered-down phone can only be located for a short time after it loses power.

You do not need to do anything else after turning it on. Find My iPhone runs in the background automatically. If you lose your device, you can locate it from any other Apple device or from a web browser.

Key Takeaways

  • Find My iPhone is turned on through Settings > Your Name > iCloud > Find My, and requires your Apple ID password to activate.
  • Your device location is encrypted and sent to Apple's servers, so you can find it from another iPhone, iPad, Mac, or iCloud.com.
  • Find My iPhone works on locked, offline, or recently powered-down devices, though a turned-off phone can only be located briefly.
  • You can play a sound on your device, lock it remotely, or erase it if you believe it is lost or stolen.

What you need before you start

You need an Apple ID and your Apple ID password. If you do not have an Apple ID, you create one for free at appleid.apple.com or during iPhone setup. Your Apple ID is the account you use to sign into iCloud, the App Store, and other Apple services.

You also need to be signed into iCloud on your iPhone. Most iPhones are signed into iCloud automatically during setup, but if yours is not, go to Settings > Your Name and sign in with your Apple ID. Find My iPhone only works when you are signed into iCloud.

How to locate your iPhone after setup

Once Find My iPhone is on, you can find your device from another Apple device or from a computer. On another iPhone or iPad, open the Find My app (it is built in). Tap the Devices tab at the bottom, then tap your missing device. The map shows its location, and you can play a sound, lock the device, or erase it.

From a Mac, open the Find My app the same way. From a Windows computer or any web browser, go to iCloud.com, sign in with your Apple ID, and click Find My iPhone. The process is the same: select your device from the list and choose what you want to do.

If your device is offline or powered off, Find My iPhone shows its last known location. Some devices can send their location even when offline if they have been updated to support this feature — this is called Find My network. The map updates when your device comes back online or is powered on.

Playing a sound and locking your device remotely

If you think your iPhone is nearby but you cannot find it, you can play a sound from the Find My app. Select your device and tap Play Sound. Your iPhone will play an alert for two minutes, even if it is on silent mode. This works whether the device is locked or unlocked.

If you believe your device is lost or stolen and you do not want someone else to access it, you can lock it remotely. In Find My, select your device and tap Lock (or Activate if the device is not yet locked). You set a new passcode, and the device locks immediately. The person holding it cannot unlock it without that passcode.

You can also add a message and phone number to the lock screen so someone who finds your device can contact you. This message appears on the lock screen even before the device is unlocked.

Erasing your device if it is lost or stolen

If you cannot find your device and you are certain it is lost or stolen, you can erase it remotely to protect your data. In Find My, select your device and tap Erase This Device. This removes all data from your iPhone, iPad, or Mac and returns it to factory settings. The device will no longer appear in Find My after it is erased.

Erasing is permanent and cannot be undone. You cannot locate the device after erasing it. Only erase your device if you are sure you will not find it and you want to prevent someone else from accessing your photos, messages, passwords, and other personal information.

After erasing, your device can still be activated by anyone who has it, but they will not have access to your data. If you later find your device, you can sign back in with your Apple ID and restore from a backup.

Turning off Find My iPhone

If you want to turn off Find My iPhone, go to Settings > Your Name > iCloud > Find My and toggle it off. You will need to enter your Apple ID password to confirm. When Find My iPhone is off, you will not be able to locate your device if it is lost.

You might turn it off if you are selling or giving away your device and want to remove it from your account. Before you do, make sure you have erased the device and signed out of iCloud, or the new owner will not be able to use it without your Apple ID password.

Frequently Asked Questions

Does Find My iPhone work if my phone is turned off?

Find My iPhone can locate a powered-off device for a short time after it loses power, depending on your device model and iOS version. After that window closes, the app shows the last known location. Some newer iPhones can send their location even when off through the Find My network, but this is not available on all models.

Can someone else see my location if I have Find My iPhone on?

No. Your location is private and encrypted. Only you can see your device's location through the Find My app or iCloud.com. You can choose to share your location with specific people through the Find My app's People tab, but this is separate from Find My iPhone and requires you to turn it on manually.

What happens if I erase my device and then find it?

If you erase your device remotely and then find it, you can sign back in with your Apple ID and restore your data from an iCloud backup. The device will be in factory settings until you do this. You cannot undo an erase, but you can restore everything if you have a backup.

Do I need a cellular plan for Find My iPhone to work?

Find My iPhone works over Wi-Fi or cellular data. If your device is connected to Wi-Fi, it does not need a cellular plan. If you want to locate a device that is away from Wi-Fi, it needs either a cellular plan or the ability to connect to the Find My network through nearby Apple devices.

Can I set up Find My iPhone for someone else's device?

No. Find My iPhone must be set up on the device itself using that person's Apple ID. You cannot turn it on remotely or set it up for another person's iPhone. The person who owns the device needs to go through Settings and turn it on themselves.
