How to switch to a different Apple ID on your iPhone
To change your Apple ID on an iPhone, you sign out of your current account in Settings, then sign in with a different Apple ID. The process takes about five minutes and doesn't erase your phone — but you will lose access to photos, notes, reminders, and other data stored in iCloud under your old account unless you back them up first.
The steps differ slightly depending on whether you have an older iPhone with a home button or a newer one with Face ID. Both paths lead to the same result: your phone is now linked to a new Apple ID, and you can download apps, use iCloud, and make purchases under that account instead.
Key Takeaways
- Signing out of your Apple ID in Settings removes access to iCloud data tied to that account, so back up photos, notes, and reminders before you start if you want to keep them.
- You need to know the password for your old Apple ID to sign out, or you will be stuck on the sign-out screen.
- After signing out, you sign in with your new Apple ID credentials in the same Settings menu.
- If you forgot your old Apple ID password, you can use "Forgot Password" on the sign-out screen or reset it on Apple's website before attempting to change accounts.
Back up your data before signing out
When you sign out of your Apple ID, your iPhone stops syncing with iCloud. Any photos, notes, reminders, contacts, or calendar events stored only in iCloud will no longer appear on your phone after you sign out. If you want to keep this data, back it up before you proceed.
The easiest way is to back up to iCloud one final time: go to Settings, tap your name at the top, select iCloud, then tap iCloud Backup and choose "Back Up Now." This saves everything tied to your old account. Alternatively, you can connect your iPhone to a Mac or Windows computer and use Finder (Mac) or iTunes (Windows) to create a local backup on that device.
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. You will be asked to enter the password for your current Apple ID — this is a security step to prevent someone else from locking you out of your account. Type the password and tap "Turn Off."
A menu will appear asking what you want to do with your iCloud data. Choose "Keep on My iPhone" if you want local copies of your notes, reminders, and calendar events to stay on the phone (they will no longer sync to iCloud). Choose "Delete from My iPhone" if you want to remove them entirely. After you choose, tap "Sign Out" again to confirm.
What to do if you don't remember your old password
If you reach the password screen and cannot remember it, tap "Forgot Password?" on that same screen. Apple will walk you through resetting it using your recovery email or phone number. You can also go to iforgot.apple.com on any web browser and reset your password there before attempting to sign out on your phone.
If you do not have access to your recovery email or phone number, you will need to contact Apple Support. They can help you regain access to your account or, in some cases, help you remove the account from your phone without the password — but this process takes longer and requires proof of identity.
Sign in with your new Apple ID
After you sign out, the Settings screen will return to the top. Tap "Sign in to your iPhone" and enter the email address and password for your new Apple ID. If you do not have an Apple ID yet, you can create one during this step by tapping "Don't have an Apple ID or forgot it?" and following the prompts.
You will be asked to set up two-factor authentication if your new Apple ID does not already have it enabled. This adds a security layer by requiring a code from a trusted device when you sign in from a new location. Follow the on-screen steps to complete setup. Your iPhone will then sync with iCloud under your new account.
Restore your data to the new account
If you backed up your phone to iCloud before signing out, you can restore that backup to your new Apple ID account. Go to Settings, tap your name, select iCloud, and look for an option to restore from backup. Note that this will restore data from your old account, so you may see duplicate contacts or calendar events if your new account already has some of the same information.
Alternatively, if you created a local backup on a Mac or Windows computer, connect your iPhone to that computer and use Finder or iTunes to restore from that backup. This method gives you more control over what gets restored and is useful if you want to keep your new account's data separate from your old account's data.
Troubleshooting common problems
If you see a message saying "This iPhone is linked to an Apple ID" and you cannot proceed, your phone may have Activation Lock enabled. This is a security feature that prevents someone from erasing your phone and using it without permission. You will need to sign in with the original Apple ID to disable it, or contact Apple Support if you do not have access to that account.
If your new Apple ID will not sign in, make sure you are using the correct email address and password. If you recently changed your Apple ID email address, use the new email, not the old one. If you still cannot sign in, go to iforgot.apple.com and reset your password, then try again on your phone.
Frequently Asked Questions
Will changing my Apple ID delete everything on my iPhone?
No. Signing out of your Apple ID removes access to iCloud data tied to that account, but it does not erase your phone's storage. Photos, apps, and files stored locally on your device stay on the phone. Only data synced through iCloud — like notes, reminders, and calendar events — will stop appearing after you sign out.
Can I use two Apple IDs on the same iPhone?
No. An iPhone can only be signed in to one Apple ID at a time for iCloud and purchases. However, you can set up multiple user accounts on the phone itself if you want different people to use it, and each account can have its own Apple ID. This is different from signing out and signing in with a new account.
What happens to my apps when I change my Apple ID?
Apps you downloaded with your old Apple ID will remain on your phone, but you will not be able to update them through the App Store under your new Apple ID. You can either delete them and re-download them with your new account, or keep them as they are. In-app purchases tied to your old Apple ID will not transfer to your new account.
How long does it take to change my Apple ID?
The sign-out and sign-in process usually takes five to ten minutes. However, if you are backing up your data first or restoring from a backup afterward, the total time depends on how much data you have and your internet speed. A full backup or restore can take anywhere from a few minutes to an hour.
Can I change my Apple ID back to my old one later?
Yes. You can sign out of your current Apple ID and sign back in with your old one at any time, as long as you remember the password. Your old iCloud data will be accessible again once you sign in. If you backed up your phone before switching, you can also restore that backup to recover data from that time period.
