What happens when you change your Apple ID
Your Apple ID is the account you use to sign into iCloud, the App Store, Apple Music, and other Apple services across your devices. When you change it, you are replacing the email address or phone number associated with that account — not creating a new account or losing your data.
The process itself is straightforward, but the timing matters. Apple requires you to wait three days after changing your ID before you can change it again, so choose carefully. Your apps, photos, purchases, and settings stay with your account; you do not lose anything by switching the email address you use to sign in.
The most common reason to change your Apple ID is that you no longer use the email address it is tied to, or you want to consolidate multiple Apple accounts into one. You can change it on any device where you are signed in, or through Apple's website.
Key Takeaways
- You change your Apple ID by going to Settings on your device, tapping your name, then Account, then selecting the option to change your email or phone number.
- On a Mac, the same process lives in System Settings under your name, then Account, then the option to edit your Apple ID.
- You can also change your Apple ID through appleid.apple.com on any web browser without touching your device settings.
- After you change your ID, you will need to sign out and back in on any device that uses the old one, using your new email address.
- Apple prevents you from changing your ID again for three days after you make a change, so verify the new address is correct before you confirm.
Changing your Apple ID on iPhone or iPad
Open Settings and tap your name at the top of the screen. This takes you to your account page. Tap Account, then scroll down and tap Name, Phone Number, Email. You will see your current Apple ID listed here.
Tap Edit next to your Apple ID. You can now enter a new email address or phone number. Apple will send a verification code to whichever address or number you choose — you must have access to it to complete the change. Enter the code when it arrives, and your Apple ID is updated.
After you change your ID, you may see a prompt asking you to sign out and back in. Do this on any device where you use that account, because the old ID will no longer work for signing in. Use your new email address or phone number when you sign back in.
Changing your Apple ID on Mac
Click the Apple menu in the top-left corner and select System Settings. Click your name at the top of the sidebar on the left. You will see your account information displayed.
Look for the option that says Account or Edit Account Details. Click it, then find the field showing your current Apple ID. Click Edit and enter your new email address or phone number. Apple will send a verification code to the new address — enter it to confirm the change.
Once the change is complete, you may need to sign out of iCloud and sign back in using your new ID. Go back to System Settings, click your name, then look for the option to sign out. Sign back in with your new email address.
Changing your Apple ID through the web
You can change your Apple ID without touching your device by visiting appleid.apple.com in any web browser. Sign in with your current Apple ID and password. Click Account in the top menu, then look for the section labeled Sign-In and Security or Personal Information.
Find the field showing your Apple ID email address. Click Edit next to it and enter your new email address. Apple will send a verification code to both your old and new addresses — you must confirm the code sent to the new address to complete the change.
This method is useful if you are away from your devices or prefer to handle account changes on a computer. The change takes effect when ready across all your Apple services.
What to do after you change your Apple ID
On any device where you were signed in with your old Apple ID, you will need to sign out and sign back in. Go to Settings (or System Settings on Mac), tap your name, scroll to the bottom, and tap Sign Out. When prompted, choose to keep a copy of your iCloud data on the device — this prevents you from losing photos, notes, or other synced information.
Sign back in using your new Apple ID email address and your password. Your device will re-sync with iCloud using the new account. This usually takes a few minutes depending on how much data you have.
If you use your Apple ID to sign into apps or services outside of Apple — like some third-party apps that offer "Sign in with Apple" — those will continue to work. You do not need to update them separately.
If you cannot remember your password after changing your ID
If you change your Apple ID and then forget your password, you can reset it at appleid.apple.com. Click Forgot Password, enter your new Apple ID, and follow the steps. Apple will send a reset link to the email address associated with your account or ask you to answer security questions you set up previously.
If you cannot access the email address you changed your ID to, you have a problem — you will not be able to reset your password or sign back into your devices. This is why it is important to verify the new email address works before you confirm the change. If this happens, contact Apple Support through appleid.apple.com and be ready to answer security questions to prove you own the account.
Frequently Asked Questions
Can I change my Apple ID back to the old one?
Yes, but only after three days have passed since you made the change. After three days, you can change your Apple ID again by following the same steps. You cannot change it back when ready.
Will I lose my apps or photos if I change my Apple ID?
No. Your apps, photos, documents, and all other data stay with your account. Changing the email address does not affect what is stored in iCloud or what you have purchased from the App Store.
Do I have to change my Apple ID on all my devices at once?
No. You can update one device at a time. However, you will not be able to sign into a device with your old Apple ID once you have changed it, so plan to update each device before you need to use it.
What if I have two Apple IDs and want to merge them?
Apple does not merge accounts directly. If you have purchases or data in two separate accounts, you will need to decide which one to keep using. You can change one ID to match the other, but the data in the old account will not transfer — you would need to manually move photos, notes, or other files.
Can I use a phone number instead of an email address as my Apple ID?
Yes. When you change your Apple ID, you can enter a phone number instead of an email address. Apple will send verification codes to that number via text message. However, most people find an email address more reliable for account recovery.
