How to Reset iPhone: Factory Reset & Activation Lock
A factory reset promises a completely blank iPhone — but whether that blank state actually happens depends on whether the Apple ID on the phone still belongs to the original owner. Apple’s security features block anyone else from simply erasing and reusing a device.

How do I factory reset my iPhone?
Back up before resetting
- Use iCloud or a computer to create a full backup before any erase step.
- Verify the backup is complete before proceeding.
Before an erase, Apple recommends backing up to iCloud or a computer to avoid permanent data loss (Apple Support pre‑erase backup guidance).
Erase all content and settings
- Navigate to Settings > General > Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- The device will ask for the Apple ID password if Find My is enabled.
The exact path is Settings > General > Transfer or Reset iPhone > Erase All Content and Settings (Apple Support erase procedure).
Restore from backup or set up as new
After the erase completes, the iPhone restarts into the setup screen. The new user can either restore data from a recent backup or proceed with a fresh start.
A factory reset erases all local data, but if Find My is on, the Activation Lock survives the wipe. The phone cannot be set up by anyone else until the original owner removes the device from their Apple ID (Apple Support Activation Lock warning).
The implication: A factory reset is fully under your control as long as the device is logged into your Apple ID and Find My is turned off.
The pattern: Ownership status determines whether the standard reset path works—no ambiguity once you control the Apple ID.
How do I force my iPhone to reset?
Force restart by model
- iPhone 8 and later: press and release Volume Up, press and release Volume Down, then press and hold the Side button until the Apple logo appears.
- iPhone 7, iPhone 6s or earlier: the button sequence differs by generation.
The force restart method depends on the iPhone model. Apple publishes the sequences for each generation on its support site.
When to use force restart
Use a force restart when the screen is frozen, unresponsive, or the device will not shut down normally. It does not erase apps or data.
Force restart vs factory reset
A force restart reboots the device and clears the temporary session. A factory reset wipes the entire system and—if Find My is active—triggers Activation Lock.
Why this matters: A force restart is a temporary fix for a frozen screen, not a permanent reset. It resets the session, not the device’s identity or data.
Remote erase from Find My locks the phone just as tightly as a manual factory reset. Only the owner’s Apple ID can turn it back on (Apple Find My documentation).
The distinction between a force restart and a factory reset is clear: one reboots, the other wipes—and only one triggers Activation Lock.
How do I reset my iPhone without losing anything?
Reset All Settings
- Keeps photos, messages, and apps intact.
- Resets Wi‑Fi networks, Bluetooth pairings, wallpaper, and privacy permissions.
Reset All Settings is available under Settings > General > Transfer or Reset iPhone > Reset All Settings.
Back up before an erase
No reset method changes personal data unless you choose Erase All Content and Settings. But backing up before any reset that could remove data is the safest habit.
Reinstall iOS without erasing personal data
You can reinstall iOS via a recovery mode update without losing media and app data. This is an option when system files are corrupted but personal data is still accessible.
The pattern: ‘Reset All Settings’ is the only path that resets the system configuration while leaving photos, messages, and apps untouched. Every other reset method either removes data or leaves the device tied to the previous owner.
How do I reset an iPhone for a new user?
Sign out of Apple ID and Find My
- Go to Settings > your name > Find My and turn Find My iPhone off.
- Sign out of iCloud so the next owner can use the device with their own account.
Turning off Find My before an erase ensures Activation Lock will not transfer to the next user (Apple Support owner transfer guidance).
Erase all content and settings
Once Find My is off and the account is signed out, perform a standard Erase All Content and Settings from the Settings menu.
Activation Lock must be off
After the erase, the iPhone should present the hello screen with no Activation Lock. If Activation Lock is still active, only the previous owner can remove it by deleting the device from their Apple ID account.
The catch: If Activation Lock is still on, the new user sees a black screen demanding the previous owner’s password. No amount of erasing from the Settings menu removes it — only the original owner can turn it off.
Can you factory reset an iPhone without Apple ID or passcode?
When Activation Lock blocks the reset
- A standard factory reset asks for the Apple ID password when Find My is enabled.
- Activation Lock prevents reactivation even after the device is erased.
Apple’s Activation Lock is designed to prevent anyone other than the owner from using the iPhone (Apple Support Activation Lock definition).
If you forgot your Apple ID password
Apple account recovery can help, but only after verifying your identity. The process requires access to trusted devices or recovery methods linked to the account. Success is not guaranteed when contact information has changed.
If you found or bought a locked iPhone
If Activation Lock is on, the previous owner must remove the device from their Apple ID account. Apple may assist with an Activation Lock support request if you can provide proof of purchase.
What this means: Apple designed Activation Lock to require the Apple ID password even for a full device reset. Without it, the only paths involve the previous owner or proof of purchase.
The consequence for anyone without the original Apple ID is binary: either the previous owner helps, or the device remains locked.
Steps to factory reset an iPhone for the current owner
- Back up your data. Use iCloud or a computer to save photos, messages, and app data. (Apple Support backup guidance)
- Turn off Find My iPhone. Go to Settings > your name > Find My and toggle it off.
- Sign out of your Apple ID. This ensures the next owner can activate the phone with their account.
- Erase all content and settings. Navigate to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. The device will ask for your Apple ID password if Find My is still on.

— Apple Support (Activation Lock guidance)
“When Activation Lock is removed, someone else can activate the device and connect it to their Apple Account.”

For anyone buying a secondhand iPhone, the single most important step happens before you hand over the money: watch the seller sign out of their Apple ID and turn off Find My. Without that, the device stays locked to them, and no factory reset or third‑party tool can change it. Apple’s Activation Lock is designed for exactly this moment — and it works exactly as intended.

Frequently asked questions
Can a stolen iPhone be wiped clean?
If Find My is on, the device cannot be reactivated without the original owner’s Apple ID. Remote wipe via Find My is possible by the owner, which erases data but keeps Activation Lock active against the thief (Apple Support remote erase details).
Can you override the passcode on an iPhone?
No, the device passcode is stored locally and cannot be bypassed through normal means. A factory reset from recovery mode wipes the passcode but requires the Apple ID password if Find My is on.
What is the secret code to unlock an iPhone?
There is no secret unlock code for modern iPhones. Browser‑based codes are a persistent myth. Apple’s security relies on the Apple ID password and, in some cases, the device passcode.
How do I remove previous owner’s Apple ID from an iPhone?
Only the previous owner can remove the device from their Apple ID account by signing in to iCloud.com/find or the Find My app and selecting Remove This Device. Apple can assist with proof of purchase.
Can an activation lock be removed without a previous owner?
Only with proof of purchase through Apple’s Activation Lock support request process. Without the previous owner or proof of purchase, the lock cannot be removed.
I forgot my Apple ID password and my phone number has changed. How can I reset it?
Apple account recovery can help, but only after verifying your identity. Success is not guaranteed without access to a trusted device or recovery email. If the phone is locked to a previous owner, they must initiate the removal.
