What happens when you change your Apple ID

Changing your Apple ID means switching the account you use to sign into Apple services — iCloud, the App Store, Apple Music, iMessage, and others. When you change it, you're not deleting your old account; you're moving to a different one. Your old account stays active unless you close it separately.

The process differs depending on what you're trying to do. If you want to use a different email address with your current account, that's simpler than switching to an entirely different Apple ID. If you're switching to a new ID, you'll need to sign out of your devices, then sign back in with the new credentials.

One important detail: your purchases, photos, and other data tied to your old ID don't automatically move to the new one. You'll need to decide what to transfer and how before you start.

Key Takeaways

  • Changing your Apple ID email address takes minutes on any device, but switching to a completely different Apple ID requires signing out and back in on each device separately.
  • Your old account and everything in it stays active after you change — you must close it manually if you want it gone.
  • Photos, purchases, and subscriptions stay with the account they were bought on; moving them requires downloading and re-uploading or repurchasing.
  • Two-factor authentication must be turned on before you can change your Apple ID email address, and you'll need access to your old email to confirm the change.

Changing your Apple ID email address on iPhone or iPad

This is the fastest route if you want to keep your account but use a different email. Go to Settings > tap your name at the top > Name, Phone Numbers, Email. Look for the section labeled Reachable At — this shows your current Apple ID email and any aliases.

Tap Edit, then tap the red minus sign next to the email you want to remove. Confirm the removal. Then tap Add Email or Phone Number, enter your new email, and tap Next. Apple will send a verification code to that new email. Enter the code, and you're done.

Your Apple ID email is now the new one. All your devices will stay signed in — nothing logs you out. This works only if you have two-factor authentication turned on. If you don't, go to Settings > your name > Password & Security and turn it on first.

Changing your Apple ID email address on Mac

Open System Settings (or System Preferences on older macOS versions), then click your name in the sidebar. Click Name, Phone Numbers, Email. Find Reachable At and click Edit.

Click the minus sign next to the email you want to remove, then click Add Email or Phone Number. Type your new email and click Next. Apple sends a code to the new address — enter it to confirm. Your Apple ID email updates immediately.

Switching to a completely different Apple ID

If you're moving to an entirely different account (not just changing the email on your current one), you'll need to sign out of your current ID first, then sign in with the new one. This is more involved because you do it device by device.

On iPhone or iPad: Go to Settings > tap your name > scroll to the bottom > Sign Out. Enter your Apple ID password to confirm. You'll be asked whether to keep or remove a copy of your iCloud data on the device — choose based on whether you want that data to stay locally. Then go back to Settings > Sign In and enter your new Apple ID and password.

On Mac: Open System Settings > click your name > scroll down > Sign Out. Confirm with your password. Choose whether to keep iCloud data on the Mac. Then sign back in with your new Apple ID.

On Apple Watch: Open the Watch app on your paired iPhone > General > Reset > Erase Apple Watch. After it resets, pair it again and sign in with your new Apple ID during setup.

What you need to know about your data and purchases

Your purchases — apps, music, books, subscriptions — stay tied to the Apple ID that bought them. If you switch to a new ID, you won't see those purchases in the App Store or Apple Music on that new account. You can't transfer them.

Photos in iCloud stay with your old account. If you want them on your new account, download them to your computer first, then upload them to iCloud on the new account. This takes time if you have thousands of photos.

Subscriptions like Apple Music or Apple TV+ are tied to the payment method and Apple ID used to start them. If you want to keep a subscription on your new ID, you'll need to cancel it on the old account and start a new subscription on the new one.

iCloud storage plans are account-specific. If you paid for 200 GB on your old ID, that storage doesn't move to the new one. You'll start with the free tier (5 GB) on the new account unless you buy a plan there.

Turning on two-factor authentication if you haven't already

Two-factor authentication is required to change your Apple ID email. If you don't have it on, you'll need to set it up first.

On iPhone: Go to Settings > your name > Password & Security > Two-Factor Authentication > Turn On Two-Factor Authentication. You'll need a trusted phone number — Apple sends a code there to verify it's really you. Enter the code and you're set.

On Mac: Open System Settings > your name > Password & Security > Two-Factor Authentication > Turn On. Follow the same process with a trusted phone number.

Closing your old Apple ID if you no longer need it

If you've switched to a new Apple ID and want to close the old one, you can do that through Apple's account management website. Go to appleid.apple.com, sign in with your old Apple ID, and look for Account > Delete Account. Apple will ask you to confirm and may require you to settle any outstanding balance or subscriptions first.

Before you close an account, make sure you've downloaded or transferred anything you want to keep — photos, documents, purchases. Once the account is closed, you can't recover that data.

Frequently Asked Questions

Can I use the same email address for two different Apple IDs?

No. Each Apple ID must have a unique email address. If you want to use an email that's already attached to another account, you'll need to remove it from that account first, wait a few days, then use it for the new one.

What happens to my iMessage and FaceTime if I change my Apple ID?

They stay active on your devices, but they're tied to your Apple ID. If you switch to a new ID and sign out completely, iMessage and FaceTime will stop working until you sign back in with the new ID. Contacts who had your old ID may not reach you right away.

Do I have to change my Apple ID on all my devices at the same time?

No. You can change it on one device and leave others signed into the old account. However, some features like iCloud sync and Find My work best when all your devices use the same Apple ID. Mixing accounts can cause confusion with photos and documents.

Can I change my Apple ID back to my old one?

Yes. You can sign out of your current ID and sign back in with the old one on any device, as long as you still have access to that old account's email and password. Your old account and its data will still be there.

What if I forget the password to my old Apple ID before I switch?

Go to iforgot.apple.com, enter the email address for that Apple ID, and follow the steps to reset the password. You'll need access to the email address or a trusted phone number on file. Once you've reset it, you can sign out and switch to your new ID.
