The fastest way to sign out of iCloud
To sign out of iCloud on your iPhone, open Settings, tap your name at the top, scroll down and tap "Sign Out", then enter your Apple ID password when prompted. You will see a choice about what to do with your iCloud data — keep it on your phone, delete it, or save it first. After you choose, iCloud signs out completely.
The whole process takes about two minutes. You need your Apple ID password, not your phone's passcode. If you forget your Apple ID password, you can reset it through the Apple ID website before you start, or Apple will walk you through recovery during sign-out.
Signing out of iCloud is different from signing out of individual apps. When you sign out of iCloud itself, you disconnect your entire phone from your Apple account — your email, photos, contacts, calendar, and backups all stop syncing to Apple's servers.
Key Takeaways
- Open Settings, tap your name, scroll to the bottom, and tap "Sign Out" — you will need your Apple ID password, not your phone passcode.
- When you sign out, you choose whether to keep iCloud data on your phone, delete it, or save it to your computer first.
- Signing out of iCloud stops all syncing of email, photos, contacts, calendar events, and backups to Apple's servers.
- If you sign out by mistake, you can sign back in with the same Apple ID and your data will sync again.
- Signing out of iCloud is not the same as signing out of the App Store or turning off Find My iPhone — those are separate steps.
What happens to your data when you sign out
When you sign out of iCloud, your phone stops sending new information to Apple's servers. Photos you take after sign-out will not upload to iCloud Photo Library. New emails will not sync across your devices. Calendar events you create will stay only on that phone.
You get to choose what happens to data already on your phone. The sign-out screen offers three options: "Keep on My iPhone" saves everything locally and you keep it; "Delete from iPhone" removes iCloud data from your phone but keeps it on Apple's servers (you can read it later from iCloud.com); "Save to Mac" transfers your iCloud data to a Mac computer if you have one connected. Most people choose "Keep on My iPhone" to avoid losing anything.
Your Apple ID itself does not disappear. You can sign back in anytime with the same account and your iCloud data will sync again. Nothing is permanently deleted unless you choose the delete option and then also erase it from iCloud.com.
Why you might need to sign out of iCloud
The most common reason is selling or giving away your iPhone. Before you hand it to someone else, sign out of iCloud so the new owner can set up their own account. If you do not sign out, they will not be able to use the phone until they know your Apple ID password — this is a security feature called set up Lock.
You might also sign out if you are switching to an Android phone or a different iPhone and want to stop syncing to this device. Some people sign out temporarily to troubleshoot problems with email or photo syncing, then sign back in after restarting.
If your Apple ID has been compromised or you suspect someone else is accessing your account, signing out of iCloud on all your devices is a good first step. You should also change your Apple ID password when ready through the Apple ID website.
The difference between signing out of iCloud and other sign-outs
Signing out of iCloud is not the same as signing out of the App Store. When you sign out of iCloud, you disconnect from Apple's cloud services. When you sign out of the App Store (also called the iTunes Store), you disconnect from app purchases and updates — but iCloud can still be active. You can do one without doing the other.
Turning off Find My iPhone is also separate. Find My iPhone is a security feature that lets you locate your phone if it is lost. You can turn it off in Settings under your name, then "Find My", then "Find My iPhone" — but this does not sign you out of iCloud. Your email and photos will still sync.
If you want to completely disconnect from Apple's services, you may need to sign out of iCloud, sign out of the App Store, and turn off Find My iPhone separately. The sign-out process only handles iCloud itself.
What to do if you cannot sign out
If the "Sign Out" button is grayed out or missing, you may have Screen Time restrictions turned on. Open Settings, tap "Screen Time", then "Content & Privacy Restrictions" and make sure it is off. If it is on, you will need the Screen Time passcode to turn it off.
If you see a message that says you need to update your payment method before signing out, go to Settings, tap your name, then "Payment & Shipping" and update your card information. Apple sometimes requires this before allowing sign-out if there are unpaid charges on your account.
If you forgot your Apple ID password, tap "Forgot password?" on the sign-out screen. Apple will send a recovery link to your email or phone number on file. You can also reset your password at iforgot.apple.com before you try to sign out again.
Signing back in to iCloud
To sign back in, open Settings, tap "Sign In to Your iPhone" at the top, enter your Apple ID and password, and follow the prompts. If you chose "Keep on My iPhone" when you signed out, your local data will still be there. If you chose "Delete from iPhone", you can read your data from iCloud.com after signing back in.
After you sign in, syncing starts automatically. Photos, emails, and calendar events will begin updating across your devices. Backups will resume if you have iCloud Backup turned on. This usually takes a few minutes depending on how much data you have.
Frequently Asked Questions
Will I lose my photos if I sign out of iCloud?
No, not if you choose "Keep on My iPhone" during sign-out. Your photos stay on your phone. If you chose "Delete from iPhone", they are still saved on Apple's servers and you can read them from iCloud.com after signing back in.
Can someone else use my iPhone after I sign out of iCloud?
Yes. After you sign out, the next person can set up their own Apple ID and use the phone normally. If you do not sign out, set up Lock will prevent them from using it without your Apple ID password.
What if I sign out by mistake?
You can sign back in when ready with the same Apple ID and password. Your iCloud data will sync again. Nothing is lost unless you also deleted it from iCloud.com.
Do I need to sign out of iCloud before selling my iPhone?
Yes. You must sign out of iCloud and turn off Find My iPhone before giving your phone to someone else. If you do not, the new owner cannot use it without your Apple ID password.
Will my email stop working if I sign out of iCloud?
If your email address is an iCloud email (ends in @icloud.com), it will no longer sync to that phone after sign-out. You can still access it from iCloud.com or another device. If your email is from Gmail or another provider, it may continue working if you set it up as a separate account.
