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.
How to fix the approve an iPhone from another device error
- Use a verification code from another phone
- Use a trusted phone number
- Update to the latest iOS version
- Turn off 2-factor authentication

Get a verification code from your other device
Have you used another iPhone, iPad, iPod Touch, or Mac to log into your iCloud account? If you have a device that shares your iCloud account, it is where Apple sent your verification code. If you are wondering how to Approve your iPhone from another device, simply go to that device and you will find your verification code then type it on your iPhone to enable its access to iCloud.
If you aren’t sure of devices that are sharing your iCloud, you can view them or manage them from the Apple ID website. If the trusted device is running iOS 10.3 or later, the verification code will appear automatically on the screen. However, if it runs iOS 10.2 or earlier, follow these steps:
- Navigate to Settings > Your Name (Or Apple ID)
- Tap Password and Security then Get Verification Code. If a message appears showing Account Details Unavailable, tap to get the verification code then OK
- The message will disappear instantly on your iPhone allowing you to sign in
Use a trusted phone number
If you don’t have your trusted device nearby, you can add a trusted phone number where Apple will send you the verification code as a text. Follow these steps to add a trusted phone number on your iPhone.
- Tap on Didn’t get a verification code just below the Approve this iPhone message
