What happens when you change your Apple account

Changing your Apple account means signing out of one Apple ID and signing into another on your device. This affects what you can read, which photos and documents sync to your device, and which payment method Apple uses. The process itself takes about ten minutes, but you need to know what you're about to lose access to — and what stays on your device.

When you sign out, you keep the apps and files already on your device. What changes is where new purchases come from, which cloud storage syncs to this device, and which email address receives your Apple notifications. If you're switching because you have a work account and a personal account, or because you inherited a device, the steps are straightforward. If you're switching because you forgot your password, you'll need to recover that account first — or create a new one.

Key Takeaways

  • Signing out of your Apple ID keeps all apps and files on your device, but stops syncing new photos, documents, and purchases to that account.
  • You must know your current Apple ID password to sign out on iPhone, iPad, or Mac — you cannot sign out without it.
  • After you sign out and sign in with a new account, you can re-read apps you bought with the old account, but only if you sign back in to authorize each one.
  • If you cannot remember your current password, you must reset it through Apple's account recovery before you can sign out.
  • On Mac, signing out of your Apple ID also signs you out of iCloud, which means your Mac will no longer back up automatically.

Sign out on iPhone or iPad

Open Settings and tap your name at the top of the screen. Scroll to the bottom and tap Sign Out. You will see a warning that says iCloud data will be removed from this device — this means photos, notes, reminders, and anything else stored in iCloud will no longer sync here, but they stay in your iCloud account online. Tap Sign Out again to confirm.

Apple will ask for your password one more time. Type it in and tap Sign Out. If you have two-factor authentication turned on (which most accounts do), you may see a prompt asking you to confirm on another device you own — approve it. Once you see the sign-out screen, you're done with the old account.

Now tap Sign in with your Apple ID at the top of Settings. Enter the email address and password for your new account. If that account has two-factor authentication, approve the sign-in on another device when prompted. Your new account is now active, and new purchases, photos, and documents will sync to this account instead.

Sign out on Mac

Click the Apple menu in the top-left corner and select System Settings (on newer Macs) or System Preferences (on older ones). Click General on the left, then look for your account name and click Sign Out. A window will appear asking what you want to do with your iCloud data — choose Keep on Mac if you want to keep your photos and documents on this computer, or Remove if you want them deleted.

Type your password when prompted and click Sign Out. Your Mac will sign you out of iCloud and your Apple ID. Automatic backups will stop until you sign in with a new account. You'll see a sign-in screen on your Mac — enter the email and password for your new Apple ID. If two-factor authentication is on, approve the sign-in from another device.

What to do if you don't remember your password

You cannot sign out without your current password — Apple requires it as a security step. If you don't remember it, you must reset it before you can sign out. Go to iforgot.apple.com on any web browser and enter the email address for the account you're trying to leave.

Apple will ask you to verify your identity. You can choose to receive a reset link by email, or answer security questions you set up when you created the account. Follow the prompts to create a new password. Once you've reset it, return to your device and try signing out again — now you'll have the password you need.

If you don't have access to the email address anymore and you can't answer the security questions, contact Apple Support. They can verify you're the account owner through other means, but the process takes longer than a standard password reset.

Re-read apps after switching accounts

Apps you bought with your old Apple ID stay on your device after you sign out. You can use them normally. However, if you delete an app and want to read it again, the App Store will ask you to sign in with the account that purchased it. You'll need to sign back into your old account temporarily to re-read it.

To do this, open the App Store and tap your profile icon in the top-right corner. Tap Sign Out. Then tap Sign In and enter your old Apple ID email and password. Search for the app you want and tap the cloud icon to read it. Once it's installed, sign out again and sign back in with your new account. The app will stay on your device and work normally.

If you bought an app with your old account but want to keep using it with your new account, you have two options: keep the old app installed (it will work forever), or buy it again with your new account. There's no way to transfer app ownership between accounts.

Understand what syncs and what doesn't

When you sign in with a new Apple ID, only data associated with that account will sync to your device going forward. Photos taken after you sign in will sync to the new account's iCloud. Notes, reminders, and calendar events created after sign-in will sync to the new account. Contacts will sync to the new account.

Data created under your old account stays on your device but stops syncing. If you had 500 photos in iCloud under your old account, they remain on your device if you chose to keep them during sign-out, but they won't update or sync anymore. If you want to move old photos to your new account, you'll need to manually upload them or use a computer to transfer them.

Messages, email, and any third-party apps (like Spotify or Gmail) are separate from your Apple ID. Changing your Apple account does not affect them. You sign into those apps independently, so they continue working with whatever account you set them up with.

What to do if you're switching on a shared device

If multiple people use the same device and each person needs their own Apple ID, create a separate user account on the device instead of just signing out and signing in. On Mac, go to System Settings > General > Users & Groups and click the plus sign to add a new user. Each user gets their own login, their own Apple ID, and their own data.

On iPad, you can set up multiple user accounts under Settings > General > Users & Groups (iPad only — iPhone does not support multiple user accounts). Each person signs in with their own Apple ID when they use the device. This is cleaner than signing one account out and another in repeatedly, because each person's data, apps, and settings stay separate.

If you only have one person using the device at a time but you want to switch accounts occasionally, signing out and signing in works fine. Just remember that iCloud data will stop syncing until you sign in with a new account.

Frequently Asked Questions

Will I lose my photos and files if I sign out?

Photos and files on your device stay there. What changes is that new photos won't sync to your old account's iCloud anymore — they'll sync to your new account instead. If you had photos stored only in iCloud (not downloaded to your device), you can choose to keep them on the device during sign-out, but they won't sync or update.

Can I sign out without a password?

No. Apple requires your password to sign out as a security measure. If you don't remember it, reset it at iforgot.apple.com before attempting to sign out. If you can't reset it yourself, contact Apple Support.

What happens to my email if I change my Apple ID?

Your Apple ID email address and your personal email are different things. Changing your Apple ID doesn't affect Gmail, Outlook, or any other email account you use. Those apps stay signed in with whatever account you set them up with.

Do I need to sign out before selling my device?

Yes. Before you sell or give away an iPhone, iPad, or Mac, sign out of your Apple ID completely. This removes your account from the device and allows the new owner to set it up with their own account. On iPhone and iPad, also go to Settings > General > Transfer or Reset and tap Erase All Content and Settings.

Can I use two Apple IDs on one device at the same time?

Not on iPhone — you can only have one Apple ID signed in at a time. On iPad, you can create multiple user accounts, each with a different Apple ID. On Mac, you can create multiple user accounts as well. Each account is completely separate.
