Use Lost Mode in Find Devices on iCloud.com
Lost Mode lets you lock your iPhone, iPad, Mac, or Apple Watch so that others can’t 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 Apple Support article System requirements for iCloud.
What happens when you use Lost Mode or lock a lost device?
A confirmation email is sent to your Apple Account email address.
You can create a message for the device that says it’s lost and how to contact you.
For an iPhone, iPad, Mac, and Apple Watch, your device doesn’t 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, and Apple Watch, 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
Go to icloud.com/find, then sign in to your Apple Account (if necessary).
Tip: To sign in without entering a two-factor authentication code, tap
at the bottom of the window.Select the device below All Devices on the left.
If you’ve already selected a device, you can tap All Devices to return to the list and select a new device.
Tap Mark As Lost.
Follow the onscreen instructions, keeping the following in mind:
Passcode: If your iPhone, iPad, 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 an Intel-based Mac, you must create a numerical passcode, even if you already have a password set up on your Mac. This passcode is distinct from your password and is only used when you lock your Mac with Find Devices.
Family Sharing: If you’re trying to place a family member’s iPhone or iPad in Lost Mode and the device doesn’t have a passcode set, you must enter that person’s Apple Account password on this device. If you’re trying to lock a family member’s Mac, you must enter that person’s Apple Account password on this device.
Contact information: If you’re asked to enter a phone number, enter a number where you can be reached. If you’re 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 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.
Change your contact information on a lost device
After you mark your iPhone, iPad, or Apple Watch as lost, you can update your contact information.
Go to icloud.com/find, then sign in to your Apple Account (if necessary).
Select the device below All Devices on the left.
If you’ve already selected a device, you can tap All Devices to return to the list and select a new device.
