How to Fix “Approve This iPhone from Another iCloud Device Error”

Approve this iPhone. Go to one of your other devices signed in to iCloud to approve this iPhone. This is one of the most common alerts that you will get when you try to sign in to iCloud on your iPhone, especially when you’ve just updated it to iOS 10 and above.

Why does this problem appear?

Although it can be irritating, it is important to remember that Apple does this because your data security matters. This is part of two-factor authentication, which is a more secure way of logging in to iCloud. This method requires another verification, in addition to your password in order to access your account.

To remove this warning, you need to check the code Apple sends to your other trusted device then enter it on the iPhone the message appears. But what if you don’t have another iPhone on your iCloud? Well, this post will also provide you with alternate solutions if you are having problems approving your iPhone from another device.
