If you've ever owned an Apple device, you need to be familiar with the Apple ID login process. You can create an Apple ID using your third-party email account (such as Gmail or Yahoo) but an Apple domain address could not be associated with it. You may have already switched back and forth between third-party emails, but now Apple has made it possible to replace the third-party email ID with an Apple domain address.
And while Apple makes managing your Apple account much easier, by allowing you to directly use an Apple domain address to access your devices, you can't go back after performing this procedure. The big fat disclaimer attached to the Apple ID change process that you won't be able to return to a third party email address if you switch to one of the Apple domains. You will be stuck for life and if you are ready to do it, let's do it.
Change the third-party email ID on iCloud
The Apple ID change process available only for Gmail and Yahoo mail accounts . Before starting the procedure, you need to remember that you have a working Apple domain account, where email addresses end with @ iCloud.com, @ me.com or @ mac.com.
Use of iPhone, iPad and iPod Touch
Note : I tried this method on my iPhone 8 Plus with iOS 11 and it worked well. You can change the Apple ID on your iOS device if running iOS 10.3 or later.
1. On the iOS device, open Settings and touch your name (shown above) to open your account settings. Then touch to open the section "Name, phone numbers, email" .
2. Here, touch the "edit" button next to "Contactable At" is remove your current ID of Part Three by tapping the red "minus" button.
3. You will required to add a new email address, which will be used as an Apple ID, to the account before trying to remove the current one. So, tap "Keep on" to add the Apple domain address to your Apple ID.
Note : This method does not work with Apple ID accounts, which do not have an iCloud mail account linked to it. Said screen will show an error saying that @ icloud.com is not a valid email address.
4. After entering the Apple domain address, press "Next" to enter a verification number received on the above e-mail address to change your Apple ID from a third party email address to an Apple domain. And voil, you're done!
As you have just read above, the simple process to change your Apple ID and it doesn't require much work. However, you cannot change the Apple ID from the email ID currently in use to an Apple domain account if you are also setting up iCloud Mail.
I tried to change the Apple ID on my personal account but the creating a new account iCloud Mail automatically added the same to the 'Attainable At' section, as an alias. Therefore, it eliminates the need for the Apple ID change process and allows you to use third-party email or iCloud address to access your account.
Using the Apple ID account page
While it's easier to make the change on your iOS devices, you can even change the Apple ID by visiting your account page on the web. Here are the steps you need to follow:
1. Go to appleid.apple.com e sign in to your Apple account . You will be asked to verify your identity by answering two of the security questions you chose when you first set up your account.
2. In the Account section, you need to do click on the "Edit" button next to the "Reachable to" section .
3. Now, in the Apple ID section, click "Add more …" and enter the Apple domain address that you now intend to use as a new login ID.
4. Finally, you will have to do click "Continue" to see your Apple ID change if you entered a valid email address @ iCloud.com, @ me.com or @ mac.com.
Apple ID: Sign in with an Apple domain address
If you have been troubled by accessing your Apple devices with a Gmail or Yahoo email address, you can now merge your data with the Apple ecosystem by accessing your Apple domain address. The previously associated third-party email address now becomes an additional email address for your Apple account. This means that you can still access your Apple account with the third-party email address, but all communications relating to the account will be sent to the iCloud Mail account.
