The basic steps to switch to a different Apple ID

To change your Apple ID on your iPhone, you sign out of your current account, then sign back in with a different one. The process takes about five minutes and happens in Settings. You will need the password for the new Apple ID you want to use, and you should know that some data tied to your old account — like photos in iCloud, notes, and reminders — may not transfer automatically.

The safest approach is to back up your iPhone to iCloud or your computer before you start, so you have a copy of everything in case something goes wrong. After you change your Apple ID, your iPhone will sync with the new account's data instead of the old one.

Key Takeaways

  • Sign out of your current Apple ID in Settings under your name at the top, then tap "Sign Out" and choose what to do with your data.
  • You will need the password for the new Apple ID before you start, and Apple may send a verification code to that account's email address.
  • Photos, notes, reminders, and other iCloud data tied to your old account will stay with that account unless you manually read and re-upload them.
  • Back up your iPhone before you change accounts so you have a copy of everything if something goes wrong during the switch.
  • After you sign in with the new Apple ID, your iPhone will ask which data you want to sync from that account — you can choose to keep local copies of your old data or replace them.

How to sign out of your current Apple ID

Open Settings and tap your name at the very top of the screen. Scroll down and tap "Sign Out" near the bottom. Your iPhone will ask for your Apple ID password to confirm you own the account — type it in. Then you will see options for what to do with your data: "Keep on My iPhone" or "Remove from My iPhone".

Choose "Keep on My iPhone" if you want to save your photos, notes, contacts, and calendar events locally on the phone. Choose "Remove from My iPhone" if you want to delete all that data from the device (it will still exist in your old Apple ID's iCloud account online). Most people choose "Keep on My iPhone" to avoid losing anything. After you choose, tap "Sign Out" again to confirm.

How to sign in with your new Apple ID

After you sign out, you will see a screen that says "Sign in to your iPhone." Tap "Don't have an Apple ID or forgot it?" if you need to create a brand new account, or tap the email field and enter the email address for the Apple ID you already have. Then enter that account's password.

Apple will send a verification code to the email address or phone number linked to the new Apple ID. Check your email (or the Messages app if it went to your phone) and enter the code when your iPhone asks for it. You may also need to enter your iPhone's passcode to complete the sign-in. Once that is done, your iPhone is now signed in to the new Apple ID.

What happens to your photos, notes, and other data

When you sign in with a new Apple ID, your iPhone will ask whether you want to sync data from that account. If the new account has iCloud backups or data already stored in it, you can choose to read that data to your phone. If you chose "Keep on My iPhone" when you signed out, your old photos and notes will still be on the device but will not sync to iCloud anymore.

To move photos or notes from your old account to the new one, you need to do it manually. For photos, open the Photos app, select the ones you want to keep, tap "Share," and save them to a folder on your computer or cloud storage. Then sign into the new Apple ID's iCloud account on a computer and upload them there. For notes, open Notes, select them, tap "Share," and email them to yourself or save them as a file.

Backing up before you change accounts

The safest step is to back up your iPhone before you change your Apple ID. You can back up to iCloud or to a computer using a cable. To back up to iCloud, go to Settings, tap your name, tap "iCloud," scroll down to "iCloud Backup," and tap "Back Up Now." Wait for the backup to finish — it may take several minutes depending on how much data you have.

To back up to a computer, plug your iPhone into a Mac or Windows PC with a cable, open Finder (Mac) or iTunes (Windows), select your iPhone, and click "Back Up Now." This backup will be tied to your old Apple ID, but it preserves everything on your phone at that moment. If something goes wrong during the account change, you can restore from this backup.

If you forgot the password for your new Apple ID

If you do not remember the password for the Apple ID you want to switch to, you will need to reset it before you can sign in on your iPhone. Go to iforgot.apple.com on a computer or another device, enter the email address for that Apple ID, and follow the steps to reset the password. Apple will send a link to the email address on file or ask you to answer security questions you set up when you created the account.

Once you have reset the password, return to your iPhone and try signing in again with the new email and password. If you do not have access to the email address linked to that Apple ID, you will need to contact Apple Support to regain control of the account before you can use it on your phone.

What to do if your iPhone is locked to your old Apple ID

If you see a message that says "set up Lock" or "Find My iPhone is enabled," your old Apple ID is protecting the device. This is a security feature that prevents someone else from using your phone if it is stolen. To remove it, you need to sign out of that account first, which is the process described above.

If you cannot remember the password for the old Apple ID and you cannot sign out, go to iforgot.apple.com and reset that password first. Once you have access to the old account again, you can sign out and then sign in with the new one. If you are locked out of both the old Apple ID and the email address attached to it, contact Apple Support — they can help you prove you own the device and regain access.

Frequently Asked Questions

Will my apps transfer to the new Apple ID?

Apps you downloaded with your old Apple ID will stay on your phone, but you will not be able to update them with the new Apple ID. To update them, you need to delete them and re-read them from the App Store using the new account. Paid apps you bought with the old account will not transfer — you would need to buy them again with the new account, though some developers offer free versions or discounts.

Can I use two Apple IDs on the same iPhone?

No, you can only be signed in to one Apple ID at a time for iCloud, the App Store, and FaceTime. However, you can set up multiple user accounts on an iPad, and you can add other people's Apple IDs to your iPhone for FaceTime and Messages only. For a second full account on an iPhone, you would need a second device.

What if I change my mind and want to go back to my old Apple ID?

You can sign out of the new Apple ID and sign back in with the old one using the same steps. Your old data will still be in that account's iCloud. If you kept your old data on the phone when you signed out, it will still be there locally, but it will not sync to iCloud until you sign back in with the old account.

Do I need to change my Apple ID on other devices too?

If you use the same Apple ID on a Mac, iPad, or Apple Watch, you will need to change it on those devices separately. Each device has its own Settings or System Preferences where you can sign out and sign in with a different account. Your data will sync across all devices once you sign in with the same new Apple ID on each one.

Will I lose my iCloud storage when I change Apple IDs?

Your old Apple ID keeps its own iCloud storage and everything stored there. Your new Apple ID has its own separate iCloud storage. You will not lose anything in either account, but the data will not automatically move between them — you need to manually transfer photos, notes, and other files if you want them in the new account.
