How To Use Another Iphone To Find My Iphone

Use Lost Mode in Find My iPhone on iCloud.com

Lost Mode lets you lock your iPhone, iPad, iPod touch, Mac, or Apple Watch so that others can't access your personal information. You can turn on Lost Mode in Find My iPhone on iCloud.com.

Lost Mode requires a device that meets the minimum system requirements listed in the Apple Support article System requirements for iCloud.

To sign in to Find My iPhone, go to icloud.com/find.

What happens when you use Lost Mode or lock a lost device?

A confirmation email is sent to your Apple ID email address.
You can display a custom message on your device's 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. Your device can still receive phone calls and FaceTime calls.
Apple Pay is disabled for your device. Any credit or debit cards set up for Apple Pay, student ID cards, and Express Transit cards are suspended for your device. Apple Pay and student ID cards are suspended even if your device is offline. Express Transit cards are suspended the next time your device goes online. You can resume using suspended cards on your device after you unlock it and sign in with your Apple ID. See the Apple Support article Manage the cards that you use with Apple Pay.
For an iPhone, iPad, iPod touch, or Apple Watch, you see your device's current location on the map, as well as any changes in its location. If Location Services is turned off on the device, it's temporarily turned on to track your device's location.
For a Mac, you can't locate it or erase it if it's not near a previously used Wi-Fi network, and you can't change the passcode or unlock it remotely.

Turn on Lost Mode or lock a device

In Find My iPhone on iCloud.com, click All Devices, then select the device you want to put into Lost Mode or lock.

If you don't see All Devices, it's because you've already selected a device. Click the name of the current device in the center of the toolbar to access the Devices list, then select a new device.
Click Lost Mode or Lock.
Follow the onscreen instructions, keeping the following in mind:
- Passcode: If your iPhone, iPad, iPod touch, 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 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 My iPhone.
- Family Sharing: If you're trying to place a family member's iPhone, iPad, or iPod touch in Lost Mode and the device doesn't have a passcode set, you must enter that person's Apple ID password on this computer. If you're trying to lock a family member's Mac, you must enter that person's Apple ID password on this computer.
- 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, iPod touch, or Apple Watch as lost, you can update your contact information.

In Find My iPhone on iCloud.com, click All Devices, then click the iPhone, iPad, iPod touch, or Apple Watch that's in Lost Mode in the Devices list.

If you don't see All Devices, it's because you've already selected a device. Click the name of the current device in the center of the toolbar to access the Devices list, then select a new device.
Click Lost Mode, change the information, then click Done.

Turn off Lost Mode on an iPhone, iPad, iPod touch, or Apple Watch

In Find My iPhone on iCloud.com, click All Devices, then select the device that's in Lost Mode.
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.

Note: If you had any cards suspended when you put your device in Lost Mode (credit or debit cards for Apple Pay, or student ID cards or Express Transit 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

In Find My iPhone on iCloud.com, click All Devices, then select the Mac that's locked.

If you don't see All Devices, it's because you've already selected a device. Click the name of the current device in the center of the toolbar to access the Devices list, then select a new device.
Click Unlock, then follow the onscreen instructions to verify your identity with your Apple ID password.
Once you have your passcode, enter it on your Mac.

You can also use Find My on any device that's signed in with the same Apple ID. See Use Find My to locate people, devices, and items.

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.
