Whether you’re selling your old device, fixing a software glitch, or handing it down to a family member, knowing how to erase iPhone is one of the most important skills you can have. A full erase wipes your personal data, photos, apps, and settings leaving the phone clean and ready for its next owner. This guide walks you through every method, step by step, in plain English.
Why You Might Need to Erase Your iPhone
There are several good reasons to wipe your iPhone completely:
- Selling or trading in your device and want to protect your privacy
- Giving your iPhone to a friend or family member
- Fixing persistent software bugs that a regular restart won’t solve
- Preparing a refurbished iPhone for resale (if you’re a seller)
- You forgot your passcode and need to start fresh
- Responding to a theft and need to remotely wipe iPhone data permanently
No matter the reason, Apple gives you multiple ways to do it safely.
Before You Erase: Quick Checklist
⚠️ Warning: Once you erase all content and settings on your iPhone, the process cannot be undone. Make sure you complete the steps below first.
Before you wipe iPhone data permanently, run through this quick checklist:
- ✅ Back up your iPhone to iCloud or your computer
- ✅ Sign out of iMessage (Settings → Messages → toggle off iMessage)
- ✅ Turn off Find My iPhone (Settings → [Your Name] → Find My → toggle off)
- ✅ Sign out of Apple ID / iCloud (Settings → [Your Name] → Sign Out)
- ✅ Unpair Apple Watch if connected
- ✅ Remove your SIM card if you’re passing the phone to someone on a different carrier
Method 1: Erase iPhone Directly from Settings
This is the easiest and most common method. It works on any iPhone running iOS 15 or later — including iPhone 12, 13, 14, 15, and 16.
Steps for iOS 16 and Later
- Open the Settings app on your iPhone.
- Tap General.
- Scroll down and tap Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- Tap Continue and follow the on-screen prompts.
- Enter your iPhone passcode if asked.
- Enter your Apple ID password to turn off Activation Lock.
- Tap Erase iPhone to confirm.
Your iPhone will restart and begin the erase process. It usually takes 2–5 minutes.
Steps for iOS 15 and Earlier
- Open Settings → General.
- Scroll down and tap Reset.
- Tap Erase All Content and Settings.
- Enter your passcode, then confirm.
💡 Pro Tip: If you want to do a factory reset iPhone to factory settings but keep your Apple ID active on the device, skip the “Sign Out” step during the erase wizard — you’ll be prompted to keep or remove your Apple ID at the end.
Method 2: Erase iPhone Remotely via iCloud (Find My)
Need to erase iPhone remotely because the phone isn’t with you? Maybe it was lost or stolen. You can wipe it using Apple’s Find My network — from any browser or device.
This is sometimes called erase iPhone from iCloud or using Find My to erase iPhone remotely.
How to Erase iPhone from iCloud
- On any device or computer, go to icloud.com.
- Sign in with your Apple ID and password.
- Click Find My (or go to icloud.com/find).
- Click All Devices at the top of the map.
- Select your iPhone from the list.
- Click Erase iPhone.
- Follow the prompts to confirm.
⚠️ Note: The erase will begin the next time your iPhone connects to the internet. Once erased, you can no longer track its location using Find My.
This method is perfect for protecting your personal data if your phone is lost. It’s also a valid way to erase iPhone remotely with Find My even if you have no physical access to the device.
Method 3: Erase iPhone Using a Computer (iTunes or Finder)
If your iPhone won’t turn on, is stuck in a reboot loop, or you simply prefer a computer-based method, you can erase iPhone with iTunes (Windows or macOS Mojave and earlier) or Finder (macOS Catalina and later).
How to Erase iPhone with a Computer
- Connect your iPhone to your Mac or PC using a Lightning or USB-C cable.
- Open Finder (Mac) or iTunes (Windows/older Mac).
- If prompted, trust the computer on your iPhone.
- Select your iPhone when it appears in the sidebar.
- Click Restore iPhone.
- Click Restore again to confirm.
iTunes or Finder will download the latest iOS firmware and erase the device completely.
💡 Note: This method also updates your iPhone to the latest iOS version available. The restore process can take 10–20 minutes depending on your internet speed.

Method 4: How to Erase iPhone If It’s Locked
Forgot your passcode? Can’t remember your Apple ID? Here’s what you can do.
Option A: Use Recovery Mode (No Passcode Needed)
This method lets you erase iPhone without Apple ID access — as long as you use a computer.
- Connect your iPhone to a Mac or PC.
- Force restart into Recovery Mode:
- iPhone 8 and later: Quickly press Volume Up, then Volume Down, then hold the Side button until you see the Recovery Mode screen.
- iPhone 7/7 Plus: Hold Volume Down + Side button simultaneously.
- iPhone 6s and earlier: Hold Home + Power button simultaneously.
- When Finder or iTunes detects a device in Recovery Mode, click Restore.
- Confirm the restore — this will erase iPhone without Apple ID password.
⚠️ Important: If Activation Lock is still enabled (Find My is on), you’ll need to enter your Apple ID after the erase completes. Recovery Mode bypasses the passcode — but not the Apple ID.
Option B: Use Apple Support’s iForgot Tool
Visit iforgot.apple.com to reset your Apple ID password before using any of the above methods.
Option C: Erase via Settings After Failed Passcode Attempts
If you enter the wrong passcode 10 times in a row, iOS will automatically offer an “Erase iPhone” option. This feature must be enabled in advance under Settings → Face ID & Passcode → Erase Data.
Comparison Table: Which Method Is Right for You?
| Situation | Best Method | Requires Apple ID? | Requires iPhone? |
|---|---|---|---|
| Normal erase before selling | Settings → Erase All Content | Yes | Yes |
| iPhone is lost or stolen | iCloud / Find My | Yes | No |
| iPhone is locked or broken | iTunes / Finder (Recovery Mode) | Not for erase, but for reactivation | No |
| Forgot passcode, no computer | iCloud Find My erase | Yes | No |
| Preparing for trade-in | Settings → Erase All Content | Yes | Yes |
| Forgot Apple ID AND passcode | Recovery Mode + Apple Support | Needed after erase | No |
Expert Tip
According to Apple’s official support documentation:
“Before you sell, give away, or trade in your iPhone, make sure you unpair your Apple Watch, back up your device, and sign out of iCloud.”
— Apple Support: What to do before you sell, give away, trade in, or recycle your iPhone
This three-step reminder from Apple is the single most important thing to follow before you wipe iPhone data permanently. Skipping the iCloud sign-out step leaves Activation Lock on — meaning the next user won’t be able to activate the device.
Quick Tips: How to Erase iPhone Before Selling
If you’re specifically wiping your phone for resale, here’s a condensed checklist:
- ✅ Back up everything to iCloud or a Mac/PC
- ✅ Sign out of Apple ID (this turns off Activation Lock automatically)
- ✅ Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings
- ✅ Let the erase complete — the phone will restart to the “Hello” screen
- ✅ Don’t set it up again — leave it on the language/region screen for the buyer

FAQs
How do I erase iPhone without the Apple ID password?
Use Recovery Mode with iTunes or Finder on a computer. Connect your iPhone, force restart it into Recovery Mode, and click Restore. This erases the device without needing the Apple ID password — though you’ll still need the Apple ID to reactivate after the erase.
How do I erase iPhone if I forgot my passcode?
You have two options: use Recovery Mode on a computer (see Method 4 above), or remotely erase the device through iCloud.com → Find My → Erase iPhone. Both methods bypass the passcode requirement.
How do I erase iPhone for a trade-in?
Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. Make sure you’ve signed out of iCloud first to remove Activation Lock. After the erase, leave the phone at the “Hello” setup screen — don’t complete setup.
How do I permanently erase iPhone data so it can’t be recovered?
Using the built-in Erase All Content and Settings option already encrypts and permanently deletes your data on modern iPhones (iPhone 3GS and later). There’s no need for third-party tools. Apple’s encryption makes recovery essentially impossible on current hardware.
How do I erase an iPhone 12 specifically?
The iPhone 12 uses iOS 14+ and the steps are the same as modern iPhones:
Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
If locked, use Recovery Mode: quickly press Volume Up → Volume Down → hold Side button until the Recovery screen appears.
Can I erase iPhone with iTunes?
Yes. Connect your iPhone to a Mac or PC, open iTunes (Windows or older macOS) or Finder (macOS Catalina+), select your device, and click Restore iPhone. This fully erases and reinstalls iOS.
Conclusion
Knowing how to erase iPhone properly protects your personal data and ensures a smooth handoff — whether you’re selling, trading in, or starting fresh. Here’s a quick recap:
- Selling or giving away? Use Settings → Erase All Content and Settings after signing out of iCloud.
- Lost or stolen? Use iCloud / Find My to erase remotely.
- Locked or broken? Use iTunes or Finder in Recovery Mode.
- Forgot your passcode? Recovery Mode or iCloud erase both work.
Always back up first, and always sign out of your Apple ID before handing off your device. That single step prevents Activation Lock headaches for whoever gets the phone next.
