iCloud: Lock and track your device using Lost Mode
Lost Mode locks your iOS device, Apple Watch, or Mac so that others can’t access your personal information. It also tracks any changes to the location of your iOS device or Apple Watch. If you can’t find your device, turn on Lost Mode right away using Find My iPhone on iCloud.com. If you have Family Sharing set up, you can turn on Lost Mode for family members’ devices, too. For more information, see the Apple Support article If your iPhone, iPad, or iPod touch is lost or stolen.
When your device is in Lost Mode:
You can display a custom message on the screen. For example, you may want to indicate that the device is lost or how to contact you.
Your device doesn’t display alerts or play a sound when you receive messages or notifications or if any alarms go off. You still receive phone calls and FaceTime calls.
Any credit or debit cards set up for Apple Pay on your device are suspended for your device, even if it’s offline. Apple Pay is also disabled for your device. You can resume using suspended cards on your device after you unlock it and sign in to iCloud. For more information, see the Apple Support articles Use Wallet on your iPhone or iPod touch and Use Touch ID on MacBook Pro.
Lost Mode requires an iOS device that meets minimum system requirements. You can lock a Mac or iOS 5 device, but you can’t track it. If you lock a Mac, you can’t locate it if it’s not near a previously used Wi-Fi network, and you can’t remotely change the passcode, unlock it, or erase it. With Apple Watch, you must have watchOS 3 installed to use Lost Mode.
Turn on Lost Mode or lock a device
Click All Devices, then select the device you want to track or lock.
Click Lost Mode or Lock.
Follow the onscreen instructions, keeping the following in mind:
If your iOS device or Apple Watch has a passcode, it’s required to unlock the device. Otherwise, you’re asked to create a passcode now.
If you’re locking a Mac, you must create a six digit PIN, even if you already have a password enabled on your Mac.
If you’re trying to place a family member’s iOS device in Lost Mode, and the device doesn’t have a passcode set, that person’s Apple ID password must be entered on this computer.
If you’re trying to lock a family member’s Mac, that person’s Apple ID password must be entered on this computer.
If you’re asked to enter a phone number, enter a number where you can be reached. The number appears on the device’s Lock screen.
If you’re asked to enter a message, you may want to indicate that the device is lost or how to contact you. The message appears on the device’s Lock screen.
Note: If you forget the passcode, or if you set an EFI firmware password on your Mac before it was lost, then lock it and later find it, you may need to take it to an authorized repair center to unlock it.
Track your device in Lost Mode
If you use Lost Mode, when tracking begins, you see your device’s current location, as well as any changes in its location on the map.
Note: You can’t use Lost Mode to track a Mac or iOS 5 device.
If your device is online when you put it in Lost Mode or lock it, it locks and tracking begins (if applicable). If Location Services is turned off on the device, it’s temporarily turned on to track your device’s location. A confirmation email is sent to your Apple ID email address.
If your device is offline, the passcode lock and tracking (if applicable) take effect the next time it’s online.
Turn off Lost Mode or change your contact info
You can turn off Lost Mode or unlock your device by entering the passcode. For a Mac, the passcode is the six digit PIN you set up when you locked your Mac.
For Apple Watch or an iOS device, you can also follow the steps below to change the contact information displayed on your lost device or disable Lost Mode.
Note: If your credit and debit cards for Apple Pay were suspended because you put your device in Lost Mode, when you turn off Lost Mode and sign in to iCloud, you can resume using your cards.
Click All Devices, then select the device that’s in Lost Mode.
Click Lost Mode, then change the information or click Stop Lost Mode.
Recover the PIN to unlock your Mac
Click All Devices, then select the Mac that’s locked.
Click Unlock, then follow the onscreen instructions to verify your identity with your Apple ID password.
Once you have your PIN, enter it on your Mac.
You can also use a different iOS device to turn on Lost Mode on your missing device. For more information, open Find My iPhone, tap Help, then go to “Use Lost Mode.”
If you can’t use Lost Mode because Find My iPhone isn’t set up on your lost device, see the Apple Support article If your iPhone, iPad, or iPod touch is lost or stolen.
