How to Change Your Apple ID on an iPhone

The fastest way to switch Apple IDs on your iPhone

To change your Apple ID on an iPhone, you sign out of the current ID in Settings, then sign in with a different one. The process takes about five minutes and does not erase your phone. You will need the password for the new Apple ID you want to use, and if that ID has two-factor authentication turned on (which Apple recommends), you will also need a trusted device or recovery key to complete the sign-in.

The steps differ slightly depending on whether you want to keep your data on the phone or start fresh. Most people keep their data, which means photos, contacts, and apps stay on the device but sync to the new Apple ID going forward.

Key Takeaways

Sign out of your current Apple ID in Settings > [Your Name] > Sign Out, then sign in with the new ID using its password.
If the new Apple ID has two-factor authentication enabled, you will need a trusted device or recovery key to complete the sign-in.
Your existing photos, contacts, and app purchases stay on the phone during the switch, but new backups will go to the new Apple ID.
If you forget the password to the new Apple ID, you can reset it at iforgot.apple.com before you start the sign-out process.
Some apps tied to the old Apple ID (like iCloud Drive or Apple Music) may stop working until you update them with the new ID's credentials.

Step-by-step: signing out and signing in with a new Apple ID

Open Settings and tap your name at the top of the screen. Scroll down and tap "Sign Out" at the bottom. You will see a prompt asking whether you want to keep a copy of your iPhone data on the device. Tap "Keep on My iPhone" if you want to preserve photos, contacts, calendars, and reminders. Tap "Remove" only if you want to erase all that data from the phone (you can always restore it later from a backup if needed).

Enter your Apple ID password when prompted. This confirms you own the account you are leaving. After sign-out completes, go back to Settings, tap "Sign In to Your iPhone," and enter the email address and password for your new Apple ID. If two-factor authentication is on for that ID, follow the on-screen steps to verify your identity using a trusted device or recovery key.

Once you are signed in, your iPhone will ask whether you want to restore data from a backup. If you have a backup from when you were using the new Apple ID, you can restore it now. If not, your phone will set up as new under the new ID, and you can add apps and data as needed.

What happens to your apps and data when you switch

Apps you downloaded and paid for under the old Apple ID stay on your phone and continue to work. However, you cannot update them or reinstall them using the old ID once you have signed out. To update or reinstall those apps, you will need to sign in with the old Apple ID in the App Store, or repurchase them under the new ID.

Photos, contacts, calendars, reminders, and notes that were stored locally on your phone remain there. However, if they were synced to iCloud under the old Apple ID, they will not automatically move to the new ID's iCloud account. You can manually export them or use a backup to restore them under the new ID.

iCloud Drive, Apple Music, iCloud Photos, and other subscription services tied to the old Apple ID will stop syncing. You will need to sign in with the new Apple ID in each app's settings to reconnect them. Some apps may prompt you to do this automatically.

Two-factor authentication and why you might need it

If the new Apple ID has two-factor authentication turned on, Apple requires you to verify your identity before you can sign in on a new device. This is a security measure to prevent someone else from accessing your account. You will see a prompt asking you to verify using a trusted device or a recovery key.

A trusted device is any iPhone, iPad, or Mac you have already signed into with that Apple ID. Apple will send a verification code to one of those devices, and you enter it on your iPhone to complete the sign-in. A recovery key is a long code you set up in advance in your Apple ID account settings. If you do not have a trusted device nearby, you can use the recovery key instead.

If you do not have either a trusted device or a recovery key, you will need to reset your Apple ID password at iforgot.apple.com before you try to sign in on your iPhone. This process can take a few hours or longer depending on your account security settings.

If you do not remember the password for the new Apple ID

Go to iforgot.apple.com on a computer or another device before you start the sign-out process on your iPhone. Enter the email address for the new Apple ID and follow the steps to reset the password. Apple will send a link to your recovery email address or ask you to answer security questions you set up when you created the account.

Once you have reset the password and confirmed it works by signing in on the web, go back to your iPhone and proceed with the sign-out and sign-in steps. Having the password ready before you start makes the process smoother.

Switching back to your old Apple ID

If you change your mind and want to go back to your original Apple ID, follow the same process: sign out of the new ID in Settings, then sign in with the old one. Your phone will ask whether to keep data on the device or remove it. Choose "Keep on My iPhone" to preserve everything.

If you have a backup from when you were using the old Apple ID, you can restore it after signing back in. This will bring back photos, contacts, and other data from that point in time. If you do not have a backup, your phone will straightforward continue with the data that is already on it.

When to contact Apple Support

If you cannot sign in after entering the correct password, or if you see an error message about account security, contact Apple Support. They can verify your identity and help you regain access. You can reach them through the Apple Support app, at support.apple.com, or by calling 1-800-MY-APPLE.

If you have forgotten both the password and the recovery key for the new Apple ID, Apple Support can help you verify your identity and reset your account. This process may take longer and will require proof of ownership, such as the original receipt for the device or answers to security questions.

Frequently Asked Questions

Will changing my Apple ID erase my iPhone?

No. When you sign out, you choose whether to keep your data on the phone or remove it. If you tap "Keep on My iPhone," all your photos, contacts, and apps stay there. Only the iCloud sync connection to the old ID is severed.

Can I use two Apple IDs on the same iPhone?

Not simultaneously for iCloud and the App Store. You can only be signed into one Apple ID at a time for those services. However, you can add other Apple IDs to your phone for Mail, Contacts, and Calendar if you want to access multiple accounts.

What if I paid for apps with the old Apple ID?

Those apps remain on your phone and work normally. You cannot update them or reinstall them under the new ID without repurchasing them. You can sign back in with the old ID in the App Store to update them if needed.

Do I need to back up my iPhone before switching Apple IDs?

It is a good idea. Create a backup in iCloud or on a computer using Finder (Mac) or iTunes (Windows) before you sign out. This way, if something goes wrong, you can restore your data later.

How long does it take to switch Apple IDs?

The sign-out and sign-in process usually takes five to ten minutes. If two-factor authentication is on, add a few minutes for verification. If you need to reset a password first, that can take several hours depending on your account security settings.
