If you own an Apple device such as an iPhone or iPad, sometimes a notification might appear on screen asking you to approve iCloud from another device or enter your iCloud passcode. This message can appear for some reasons. The keychain, which stores all your passwords on the device securely, might be corrupt or needs to be verified. Here is how you do it.
Verify iCloud Keychain from your Apple Device
On iPhone or iPad
Launch Settings, swipe down to iCloud, tap iCloud, then toggle off iCloud Keychain. Reboot your Apple device.
Launch Settings again, then toggle on iCloud Keychain. You will be prompted to enter your passcode. If you don’t have a passcode setup, you can do so now or use an existing code. Since I already have one, I will enter it.
This is a tricky part I discovered with Apples iCloud SMS verification. For international users, if your phone number is not accepted, do not change the country code from the US. Instead, just enter the area code followed by your phone number.
Enter your iCloud password then tap OK.
That’s it; you won’t be bothered anymore for approval request.
For OS X users, launch System Preferences, click iCloud then click Account Details. Enter your password then click OK.
Click Reset iCloud Keychain.
Enter your passcode then click Next.
Enter your phone number then click OK. Prompts to approve your device should no longer appear, well for now at least.
