Lost Mode lets you lock your iPhone, iPad, iPodtouch, Mac or AppleWatch so that others cannot access your personal information. You can turn on Lost Mode in Find Devices on iCloud.com.
Lost Mode requires a device that meets the minimum system requirements listed in the AppleSupport article System requirements for iCloud.
To sign in to FindDevices, go to icloud.com/find.
What happens when you use Lost Mode or lock a lost device?
A confirmation email is sent to your AppleID email address.
You can create a message for the device that says it is lost and how to contact you.
For an iPhone, iPad, iPodtouch, Mac and AppleWatch, your device does not display alerts or play a sound when you receive messages or notifications, or if any alarms go off. Your device can still receive phone calls and FaceTime calls.
For an iPhone, iPad, iPodtouch and AppleWatch, you see your device’s current location on the map, as well as any changes in its location.
For applicable devices, payment cards and other services are suspended.
Turn on Lost Mode or lock a device
In FindDevices on iCloud.com, select the device in the All Devices list on the left.
If you have already selected a device, you can click All Devices to return to the list and select a new device.
Click Mark As Lost.
Follow the onscreen instructions, keeping the following in mind:
Passcode and password: If your iPhone, iPad, iPodtouch or AppleWatch has a passcode, it is required to unlock the device. Otherwise, you are asked to create a passcode now. If you are locking an Intel-based Mac, you must create a numerical passcode, even if you already have a password set up on your Mac. If you are locking a Mac with Apple silicon, it is locked with your AppleID and password
WARNING: You cannot unlock a Mac online or on another device. You can only unlock it on the Mac you marked as lost.
FamilySharing: if you are trying to place a family member’s iPhone, iPad or iPodtouch in Lost Mode and the device does not have a passcode set, you must enter that person’s AppleID password on this computer. If you are trying to lock a family member’s Mac, you must enter that person’s AppleID password on this computer.
Contact information: if you are asked to enter a phone number, enter a number where you can be reached. If you are asked to enter a message, you may want to indicate that the device is lost or how to contact you. The number and message appear on the device’s locked screen.
Change your contact information on a lost device
After you mark your iPhone, iPad, iPodtouch or AppleWatch as lost, you can update your contact information.
In FindDevices on iCloud.com, select the device in the All Devices list on the left.
If you have already selected a device, you can click All Devices to return to the list and select a new device.
Click Lost Mode, change the information, then click Done.
Turn off Lost Mode on an iPhone, iPad, iPodtouch or AppleWatch
In Find Devices on iCloud.com, select the device in the All Devices list on the left.
Click Lost Mode, click Stop Lost Mode, then click Stop Lost Mode again.
You can also turn off Lost Mode by entering your passcode on the device. If you turned on Stolen Device Protection on your iPhone, you may need to use FaceID or TouchID.
Note: If you had any cards suspended when you put your device in Lost Mode (credit or debit cards for ApplePay, or student ID cards or Express Travel cards), when you turn off Lost Mode and sign back in to iCloud, you can use them again.
Recover the passcode and unlock your Mac
If you locked an Intel-based Mac, you can recover the passcode online.
In FindDevices on iCloud.com, select the Mac in the All Devices list on the left.
If you have already selected a device, you can click All Devices to return to the list and select a new device.
Click Unlock, then follow the onscreen instructions to verify your identity with your AppleID password.
When you have your passcode, enter it on your Mac.
If you locked a Mac with Apple silicon, you must enter your AppleID (or another email address or phone number on file) and password to unlock it. See the AppleSupport articles If you forgot your AppleID and If you forgot your AppleID password.
You can also use FindMy on any device that is signed in with the same AppleID. See Use FindMy to locate people, devices and items.
If you cannot use Lost Mode because FindMy is not set up on your lost device, see the AppleSupport article Find your lost iPhone or iPad with FindMy.
