Way 1: How to Update New Apple ID on iPhone in App Store
When you want to change your Apple ID or just the password, App Store and other apps in your iPhone might request the new Apple ID. After all, App Store is pretty much what Apple ID is for. This is the most common answer on how to update your Apple ID on iPhone using the App Store, but you can also go directly to your App Store and download a free app, when the update account message will pop up instantly and you can update the Apple ID from there. You can do this by following these steps.
Step 1. Find “ Settings ” on your iPhone.
Step 2. Go to " Your Name ". (first option on the menu.).
Step 3. Go to “ iTunes & App Store ”. (If your iPhone uses iOS 10.2 or earlier skip Step 2)
Step 4. If you’re signed in with the previous Apple ID, tap on it to sign out then enter the updated Apple ID and password. If you’re signed out just go ahead and enter the new Apple ID and password.
For this method to happen correctly you’ll have to remember the old account, otherwise you’ll have to take some extra steps on retrieving your old password. The only inconvenience with this option is just as you did with App Store, you’re going to have to do it on the other main Apple Apps like FaceTime, iTunes, iCloud, etc. Also if you had some apps downloaded with the old account they probably won’t update with the new account.
Way 2: How to Update New Apple ID on iPhone in Settings
If you either changed Apple ID email or decided to change password, sometimes Apple devices have a hard time keeping up and automatically updating your account for you. In this case we recommend trying a general update of Apple ID on iPhone directly from the Settings.
Step 1. Find “ Settings ” on your iPhone.
Step 2. Go to " Your Name ". (This is the Apple ID section of the menu.)
Step 3. Scroll to the bottom of the menu and tap on " Sign Out ".Also Read:Welltorrent Proxy List
Step 4. A message will pop up asking if you want to keep all of the data in your device, tap yes.
Step 5. Go back to Settings and at the top of the menu you’ll find the “ Sign In ” option, enter your new Apple ID account and password.
Step 6. Tap " Merge " to combine the data of your device with your iCloud data.
While this can be a more effective solution than the first option we saw, it still doesn’t guarantee the message will stop appearing every once in a while because some apps will have been downloaded with the previous account. Another thing to keep in mind is that, if you have more devices connected to your Apple ID, you’ll have to repeat this process in all of them.
