What happens when you change Apple accounts

Changing your Apple account means signing out of one Apple ID and signing into a different one on your device. When you do this, your device stops syncing with the old account's iCloud, App Store, and other Apple services, and starts syncing with the new account instead. Any apps, photos, or data tied to the old account may no longer be accessible on that device — though they remain in the old account's iCloud storage.

The process differs slightly depending on whether you own the device outright, share it with family members, or are handing it off to someone else. On an iPhone, iPad, or Mac, you'll sign out of Settings (or System Preferences), then sign in with the new account. The key is understanding what data stays, what moves, and what you need to back up first.

Key Takeaways

  • Sign out of your current Apple ID in Settings or System Preferences before signing in with a new one, rather than simply creating a new user account.
  • Back up your device to iCloud or a computer before switching accounts, because some data tied to the old account may not transfer automatically.
  • Apps purchased under the old Apple ID will remain on your device but won't receive updates unless you sign in with that account in the App Store.
  • If you're sharing a device with family members, create separate user accounts or use Family Sharing instead of switching the main Apple ID.
  • On a Mac, you can have multiple user accounts, each with its own Apple ID, so you don't have to sign out to let someone else use the computer.

How to sign out and sign in on iPhone or iPad

Open Settings and tap your name at the top. Scroll down and tap "Sign Out" at the bottom of the screen. You'll be asked to enter your password for the old Apple ID — this is a security step to confirm you own the account. After you sign out, your device will ask whether to keep or delete data from that account on your device. Choose "Keep on My iPhone" (or iPad) if you want to preserve photos, notes, and other data locally; choose "Delete" if you want to remove it.

Once you've signed out, go back to Settings, tap "Sign in to your iPhone" at the top, and enter the email and password for your new Apple ID. You'll be walked through two-factor authentication if it's enabled on that account. After signing in, your device will begin syncing with the new account's iCloud, App Store purchases, and other services. This can take several minutes depending on how much data needs to sync.

How to sign out and sign in on Mac

Click the Apple menu in the top-left corner and select "System Settings" (on macOS Ventura or later) or "System Preferences" (on older versions). Click "General" in the sidebar, then look for your Apple ID at the top of the window. Click your name, then click "Sign Out" in the window that appears. You'll need to enter your password for the old account. macOS will ask whether to keep your local copies of iCloud data — choose "Keep Copy" to preserve files locally, or "Remove" if you want them deleted from this Mac.

After signing out, go back to the same screen and click "Sign In" at the top. Enter the email and password for your new Apple ID, then complete two-factor authentication. Your Mac will begin syncing with the new account. If you plan to let someone else use this Mac, consider creating a separate user account for them instead of switching the main Apple ID — that way you both keep your own files and settings.

What to back up before you switch

Before signing out, back up your device to iCloud or to a computer. On iPhone or iPad, go to Settings, tap your name, tap "iCloud," then tap "iCloud Backup" and select "Back Up Now." On Mac, open System Settings, click your name in the sidebar, click "iCloud," then click "iCloud Drive" and make sure it's turned on. You can also plug your iPhone, iPad, or Mac into a computer and back it up through Finder (Mac) or the Finder window (if you have a Mac) or iTunes (if you have a Windows PC).

Backing up is especially important because some data — like photos stored in iCloud Photo Library, notes in the Notes app, and reminders — may be tied to your old account. A backup lets you restore that data later if needed. If you're switching to a new account on the same device, you won't lose the backup; it will remain in your old account's iCloud storage for 30 days after you sign out.

Apps purchased under your old account

Apps you bought or downloaded for free under your old Apple ID will stay on your device after you sign out, but they won't receive updates. To update them, you have two choices: sign in with the old Apple ID in the App Store to update those specific apps, or delete them and re-download them under your new account (if they're free or if you're willing to buy them again).

If you share an app subscription — like Apple Music or Apple TV+ — with the old account, that subscription will stop working on your device once you sign out. You'll need to subscribe under the new account, or the old account holder will need to add you to a Family Sharing group so you can share subscriptions without switching accounts.

Using Family Sharing instead of switching accounts

If multiple people use the same device and each person needs their own purchases and settings, Family Sharing is usually a better choice than switching accounts. The main account holder sets up Family Sharing in Settings (iPhone/iPad) or System Settings (Mac), then invites up to five other family members. Each person can sign in with their own Apple ID, and purchases made by any family member can be shared across all devices in the group.

On iPhone or iPad, each family member can create their own user account in Settings under "Family" — though this is different from creating a separate user account on a Mac. On Mac, you can create multiple user accounts, each with its own Apple ID, so each person can log in separately without affecting anyone else's data or settings. This approach is cleaner than repeatedly signing out and signing in with different accounts.

Troubleshooting common problems

If you're stuck on the sign-out screen or get an error message, make sure you have an internet connection and that you remember the password for your old Apple ID. If you've forgotten the password, you'll need to reset it on Apple's account recovery page before you can sign out. If two-factor authentication is enabled on your old account, you may need to approve the sign-out from another device or from a recovery key.

If apps or data don't appear after signing in with the new account, wait a few minutes for iCloud to sync. If you're missing photos or documents, check whether they were stored in iCloud or only on the old account's device. You can also sign back in with the old account temporarily to verify the data is still there, then switch back to the new account. If you're having trouble with a specific app, try signing out of that app separately in its settings, then signing back in with the new account.

Frequently Asked Questions

Can I have two Apple IDs on the same device?

On iPhone and iPad, you can only have one Apple ID signed in at a time for iCloud and the App Store. However, you can sign in to individual apps with different Apple IDs. On Mac, you can create multiple user accounts, each with its own Apple ID, so two people can use the same computer without switching accounts.

Will I lose my photos and messages when I switch accounts?

Photos and messages stored in iCloud will remain in your old account's iCloud storage after you sign out. If you want to keep them on your device, back up before signing out. Messages and photos stored only on your device (not in iCloud) will stay on the device unless you choose to delete them during sign-out.

What if I don't remember the password for my old Apple ID?

You'll need to reset it before you can sign out. Go to iforgot.apple.com, enter the email address for the old account, and follow the recovery steps. You can reset your password using a recovery email, a phone number, or a recovery key if you set one up previously.

Do I need to sign out to let someone else use my device?

Not necessarily. On Mac, create a separate user account for them with their own Apple ID. On iPhone or iPad, you can set up a separate user account through Family Sharing, or you can simply let them use your device while you remain signed in — though they'll have access to your apps and data. For privacy, signing out is the safest option.

Will my subscriptions transfer to the new account?

Subscriptions like Apple Music, Apple TV+, and iCloud+ are tied to the account that paid for them. They won't automatically transfer to your new account. You'll need to subscribe separately under the new account, or ask the old account holder to add you to a Family Sharing group to share subscriptions.
