Remove a device from Find My iPhone on iCloud.com

You can use Find My iPhone on iCloud.com to temporarily remove a device from the Devices list or turn off Activation Lock on a device you already gave away or sold.

If you set up two-factor authentication but you don't have your trusted device, you can still use Find My iPhone. Just click the Find iPhone button after you enter your Apple ID. See How to sign in to Find My iPhone on iCloud.com.

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

Remove a device from the Devices list

If you're not using a device, you can temporarily remove it from your account so it doesn't show up in your Devices list. When the device goes online again, it reappears in the list if it has Activation Lock turned on (for an iPhone, iPad, iPod touch, Mac, or Apple Watch) or is paired with your iOS or iPadOS device (for AirPods or a Beats product).

Turn off the device, or put AirPods in their case. The device must be offline before you can remove it from the Devices list.
In Find My iPhone on iCloud.com, click All Devices, then select the device you want to remove.

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 see the Devices list, then select a new device.
Click Remove from Account.

Note: You can also remove your iPhone, iPad, iPod touch, or Mac by turning off iCloud completely on that device. Turning off iCloud turns off all iCloud features on the device.

Turn off Activation Lock on a device

If you forgot to turn off Find My before you sold or gave away your iPhone, iPad, iPod touch, Mac, or Apple Watch, you can turn off Activation Lock using Find My iPhone on iCloud.com.

If you still have the device, see the Apple Support article Activation Lock for iPhone, iPad, and iPod touch, Activation Lock for Mac, or About Activation Lock on your Apple Watch.

In Find My iPhone on iCloud.com, click All Devices, then select the device you want to erase.

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.
Erase the device.

Because the device isn't lost, don't enter a phone number or message.

If the device is offline, the remote erase begins the next time it's online. You receive an email when the device is erased.
When the device is erased, click Remove from Account.

All your content is erased, and someone else can now activate the device.

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.
