Apple IDs are essential for many activities on your Apple device, such as buying items from the App Store or using iCloud. If you lose your Apple ID or if you forget your password, you’ll need to log out of your Apple ID on other devices in order to continue using those activities. To do this, open the Settings app and select the Accounts tab. Under the Accounts heading, select Apple ID and password recovery. In the next step, enter your Apple ID and password into the fields below. Click OK to finish logging out of your Apple ID on other devices.
