Every Apple device comes with an Apple ID, and if you have an iPad, removing/changing its Apple ID is remarkably simple. Apple ID is the official name for your Apple account. It's the account you use for the App Store, iCloud, Apple Music, etc. If you're the only person using your iPad, you shouldn't ever need to remove or change the Apple ID associated with it. There are, however, times when removing or switching accounts on an iPad is necessary. These are most common in scenarios where multiple people share one iPad or if someone is selling their iPad to another person.
If you need to remove/delete the Apple ID on your iPad, the steps are as follows: open the Settings app on your iPad, tap your name at the top of the screen, scroll to the bottom of the page, and tap the red 'Sign Out' button. You're then asked to enter your Apple ID password as a security measure. After entering your password, tap the 'Turn Off' button in the top right corner to disable Find My tracking for the iPad, and then choose which data/files you want to keep a copy of. Tap the 'Sign Out' button on this page, tap the 'Sign Out' button again to confirm the action, and your Apple ID is removed from the iPad.
How To Change The Apple ID On iPad
That's how to remove the Apple ID from an iPad, but what should you do if you want to change the existing Apple ID to a new one? First, you'll want to follow all of the steps above to remove the Apple ID. Once that's done, you can add the new one as follows: Open the Settings app on your iPad, tap the 'Sign in to your iPad' button at the top of the screen, tap 'Email' to enter your Apple ID email address, and tap 'Password' to enter its respective password. Follow the rest of the on-screen instructions, and within a couple of minutes, you'll have changed your iPad's Apple ID.
Now that you know how to remove and change the Apple ID on an iPad, it's also important to understand why these tips are useful. If you're getting rid of your iPad — either to recycle or sell it — removing your Apple ID from the machine is essential. You'll also want to factory reset the iPad and unpair it from your Apple account, but removing your Apple ID is an essential part of the process. There are also situations where changing the Apple ID is important. Got a pre-owned iPad from a family member? Create a new Apple ID that you want to use instead of your old one? In these situations and more, being able to change the Apple ID on an iPad is great to know.
Before you get too trigger-happy with removing or changing an iPad's Apple ID, one thing to keep in mind is what happens to your data. Anything saved locally on the iPad — such as apps, games, and other files — should remain accessible even after removing or changing Apple IDs. However, anything linked to your old Apple ID's iCloud account will be removed from the iPad. This includes data from Reminders, iCloud Mail, Siri Shortcuts, Voice Memos, etc.
In addition to linking their Apple ID, iPad owners can name the device itself, and change this information at any time. The iPad’s name is what will show up when using features like Bluetooth and AirDrop or when the hotspot is on (for iPads with cellular connectivity). To change the iPad’s name, users should go into the Settings app and tap ‘General.’ From there, they’ll need to go to ‘About’ > ‘Name,’ where they’ll see the option to type in a new name. Here, users can get creative or keep it straightforward. Then, just tap ‘Done’ to lock it in as the iPad's name.
