To turn off the iCloud feature using IOS 8.0 on the iPhone, access the settings by launching the Settings application. Press the iCloud tab, and select the Sign Out. The exact method to turn off iCloud depends on the version of the operating system installed on the device.
To turn off the feature completely, supply your current password. The application does not fully turn off without providing the password. The device also requires a password to erase or delete the account. Inputting your password is a security measure that prevents unauthorized users from deleting or accessing the iCloud account.
During the setup of the phone, provide the password of the last iCloud user signed into the account. The phone then becomes unusable until this action completes. You can also turn off the iCloud feature on your desktop that uses Windows with iTunes installed.
To turn off iCloud on your PC, go to the iCloud program on the computer. If you experience difficulty turning off the iCloud feature, take the device to your local Apple Store for assistance. In the event of forgetting your password, go to the Apple website to reset it. Apple requires a verification process and the device to reset the password.
