What Happens When You Change Your Apple Account
Changing the Apple account on your iPhone means signing out of one Apple ID and signing into a different one. Your iPhone will then sync with the new account's iCloud data, App Store purchases, and settings. The process takes about 10 to 15 minutes, but you need to know what you're signing out of first — some data stays on the phone, and some gets replaced.
Before you start, understand that signing out of your current Apple ID will remove access to iCloud backups, iCloud Photos, iCloud Mail, and any apps you bought with that account. If you sign in with a new Apple ID, the phone will sync to that account's data instead. You can keep your photos and documents by backing them up separately, or by choosing not to delete them when prompted during sign-out.
Key Takeaways
- You must know your current Apple ID password to sign out, or you'll need to use your device passcode or Face ID as a backup.
- Signing out removes access to iCloud data tied to that account, but you can choose to keep photos, contacts, and notes on the phone itself.
- After signing out, you can sign in with a new Apple ID by going to Settings > [Your Name] > Sign Out, then signing in again at the top of the same screen.
- Apps you bought with your old Apple ID will stop updating, and you'll need to repurchase them with the new account if they're not free.
- The entire process takes 10 to 15 minutes, but Apple may ask you to wait 24 hours before using certain features with the new account.
Step-by-Step: Signing Out of Your Current Apple ID
Open Settings on your iPhone and tap the banner at the very top that shows your name and profile picture. This opens your Apple ID menu. Scroll down and tap Sign Out near the bottom of the screen. You'll see a warning that says "Your data will be removed from this iPhone" — this is normal.
When you tap Sign Out, iPhone will ask for your Apple ID password. Type it in. If you don't remember the password, tap Don't Have Access to Your Apple ID? and follow the recovery steps, which usually involve your device passcode or Face ID. Once you enter the password correctly, the phone will ask which data you want to keep on the device: iCloud Photos, Notes, Reminders, Contacts, Calendars, and Safari bookmarks. Check the boxes for anything you want to stay on the phone as local data, not synced to iCloud. Then tap Sign Out again to confirm.
The phone will now remove your account from iCloud, Mail, Messages, and the App Store. This takes a few minutes. You'll see a progress screen. Do not restart your phone or turn it off during this time.
Step-by-Step: Signing In With a New Apple ID
Once sign-out is complete, go back to Settings and tap the banner at the top again. This time it will say Sign In to Your iPhone instead of your name. Tap that banner. You'll see a screen asking for an Apple ID and password. Enter the new account's email address and password.
If the new account has two-factor authentication turned on — which Apple recommends — you'll need to enter a verification code. Apple will send this code to a trusted device or phone number linked to that account. Check your email, text messages, or another Apple device for the six-digit code and enter it on your iPhone.
Next, iPhone will ask whether to merge data from your old account with the new one. For most people, the answer is no — you're switching accounts, not combining them. Tap Don't Merge. Then choose whether to turn on iCloud Photos, iCloud Drive, and other sync features. You can turn these on or off later in Settings, so don't worry about getting it perfect right now. Tap Continue and wait for the sync to finish, which usually takes 2 to 5 minutes.
What to Do About Apps You Bought With Your Old Account
Apps you purchased with your old Apple ID will stop updating once you sign out. The App Store will show them as "Installed" but won't let you update them because they're tied to a different account. You have two choices: delete them and repurchase with the new account if they're paid apps, or leave them as-is if you don't need updates.
To check which apps are tied to your old account, open the App Store, tap your profile picture in the top right, and scroll down to Purchased. Apps marked "Installed" with a cloud icon next to them are on your phone but owned by a different account. If an app is free, you can reinstall it with your new account by tapping the cloud icon. If it's a paid app, you'll need to buy it again with your new Apple ID, or contact the developer to see if they offer a way to transfer ownership.
Recovering Data From Your Old Account
If you backed up your old iPhone to iCloud with your previous Apple ID, you can still get that data back. Sign in with the old account on a computer or another device, go to iCloud.com, and read your photos, contacts, and documents. Then sign back in with your new account on your iPhone and upload that data manually, or use AirDrop to move files between devices.
For iCloud Photos specifically, if you had them turned on with your old account, those photos are still in that account's iCloud storage. You can read them from iCloud.com by signing in with the old account, clicking Photos, selecting the images you want, and downloading them to your computer. Then you can add them to your iPhone by connecting it to the computer and using Finder (on Mac) or iTunes (on Windows).
Common Problems and How to Fix Them
You forgot your old Apple ID password. Tap Sign Out in Settings, then tap Don't Have Access to Your Apple ID? when prompted for the password. Apple will ask you to verify your identity using your device passcode, Face ID, or a recovery key. If you have none of these, you'll need to visit an Apple Store or call Apple Support at 1-800-MY-APPLE.
Sign-out is stuck on a progress screen. Wait at least 10 minutes — iCloud syncing can be slow on older phones or slow internet. If it's still stuck after 15 minutes, force-restart your iPhone by pressing and releasing Volume Up, pressing and releasing Volume Down, then holding the Side button until the Apple logo appears. Do not turn off the phone; let it restart on its own. Then try signing out again.
You see "This Apple ID is being used on another device." This means the account is actively signed in somewhere else. Sign out from that device first, or wait 24 hours for Apple's servers to catch up. If you don't have access to the other device, go to iforgot.apple.com, sign in with the Apple ID, and look for a section called "Devices" or "Security" where you can remotely sign out.
Your new account won't sync iCloud Photos. Go to Settings > [Your Name] > iCloud and make sure iCloud Photos is toggled on. If it's already on but photos aren't appearing, wait 24 hours — Apple sometimes delays the first sync. If nothing appears after 24 hours, sign out and sign back in with the new account.
Frequently Asked Questions
Will I lose my text messages and call history when I change accounts?
Text messages and call history are stored on the phone itself, not in your Apple ID, so they stay on your iPhone. However, if you had iMessage turned on with your old account, new messages from people using iMessage might not come through until you sign in with the new account and wait a few minutes for the system to update.
Can I use two Apple IDs on the same iPhone?
No. One iPhone can only be signed into one Apple ID at a time for iCloud, Mail, and the App Store. However, you can set up multiple user accounts on iPad, and you can add other people's accounts to Family Sharing so they can use the phone without signing in.
What happens to my photos if I don't back them up before changing accounts?
If you choose to keep photos on the phone during sign-out, they stay there as local files. They won't sync to iCloud anymore, but they won't be deleted. If you delete them from the phone later, they're gone for good, so back them up to your computer first if you're worried.
How long does it take for the new account to fully set up?
Sign-out and sign-in usually take 10 to 15 minutes total. However, iCloud data syncing can take several hours depending on how much data you have and your internet speed. Some features like iCloud Photos may take 24 hours to fully sync.
Do I need to change my Apple ID password before signing out?
No. Your password doesn't change when you sign out. However, if you're concerned about security, you can change your password at iforgot.apple.com before signing out. Just make sure you remember the new password before you sign out, or you won't be able to complete the process.
