It happens to the best of us. You changed your code last night because you were feeling extra "security conscious," or maybe your toddler got ahold of the device and mashed buttons until the dreaded iPhone is unavailable message appeared. Now you're staring at a glass brick. You need to know how to reset passcode on iphone devices without turning your digital life into a crater. It's stressful. Honestly, it’s one of those tech moments that makes your stomach drop because our entire lives—photos, bank logins, work chats—are behind that six-digit wall.
But here’s the reality: Apple has made this process significantly easier in recent years, provided you’re running modern software. You don't always need a bulky desktop computer or a trip to the Genius Bar anymore.

The "Erase iPhone" Shortcut (iOS 15.2 and Later)
If you’re running a relatively recent version of iOS, there is a literal "emergency exit" built right into the lock screen. You don't need to panic-search for a Lightning cable just yet. After you’ve entered the wrong passcode enough times (usually seven or eight), a tiny, humble bit of text will appear at the bottom of the screen. It says Erase iPhone or Forgot Passcode?.
Tap it.
Apple will ask for your Apple ID password. This is the "kill switch" verification. Once you provide that, the phone wipes itself clean. It’s a scorched-earth policy, but it’s the only way back in if you've truly forgotten the code. The phone resets to factory settings, and you can then restore your data from an iCloud backup. If you haven't backed up to the cloud in months, yeah, you're going to lose some stuff. That’s the trade-off for the encryption that keeps your data safe from thieves.
Using a Mac or PC to Force a Reset
Sometimes the on-screen option doesn't show up. Maybe your Wi-Fi is off, or the software version is too old. When that happens, you have to go old-school. You’ll need a computer—either a Mac or a PC with iTunes installed.
First, turn off the iPhone. Then, you have to put it into Recovery Mode. This requires a specific physical "handshake" with the buttons. For any iPhone 8 or later (including the iPhone 15 and 16 series), you click and release Volume Up, click and release Volume Down, and then hold that side Power button until the screen shows a cable pointing toward a laptop. Don't let go when you see the Apple logo. Keep holding.
Once you’re in Recovery Mode:
- Plug the phone into the computer.
- Open Finder (on Mac) or iTunes (on Windows).
- A pop-up will appear saying there is a "problem" with the iPhone.
- Choose Restore.
The computer will download the latest firmware. This can take a while—sometimes 15 minutes, sometimes an hour depending on your internet speed. If the phone exits Recovery Mode while the software is downloading, just wait for the download to finish and repeat the button-holding sequence.
The iCloud.com Method
What if you're at work and don't have your personal laptop? You can actually trigger a reset from any web browser. Go to iCloud.com/find. Log in with your Apple ID credentials. You'll see a map of your devices. Select your locked iPhone and hit Erase iPhone.

This is basically a remote self-destruct. As soon as the phone connects to a network, it will wipe itself. It’s clean. It’s fast. But again, it requires that you know your Apple ID password. If you’ve forgotten both your passcode and your Apple ID password, you’re in for a much longer journey involving Apple’s account recovery process, which can take days.
Why You Can’t Just "Bypass" the Lock
There is a massive industry of "unlocking software" ads you’ll see on YouTube or sketchy tech blogs. Most of them are junk. Apple uses a hardware-based encryption chip called the Secure Enclave. It's a separate processor that handles your passcode. Even if someone rips the memory chips out of the phone, the data is encrypted. There is no magic "backdoor" button that lets you keep your data without the code. Anyone claiming they can "unlock your iPhone without losing data" is likely trying to sell you a $40 license for software that will just do exactly what the Restore method does anyway.
Restoring Your Life from the Cloud
Once the reset is finished, the iPhone will reboot to the "Hello" screen. It’ll feel like a brand-new phone. During the setup process, you'll reach a screen that asks if you want to Restore from iCloud Backup. This is the moment of truth.
Log in. Choose the most recent backup. Your apps will start downloading, your photos will trickle back into the gallery, and your messages will reappear. If you use iCloud Photos and Messages in iCloud, those sync separately from the main backup, which is a lifesaver. Even if your last full backup was a month ago, your photos from yesterday might still be safe because they sync in real-time.
The Problem with 2FA
Here is a nuance people often miss: If your iPhone is your only Apple device, and you reset it, how do you get the Two-Factor Authentication (2FA) code to log back into iCloud?
It’s a "Catch-22." You need the code to log in, but the code is sent to the phone you just wiped. In this case, you’ll need to have a "Trusted Phone Number" associated with your account. You can choose to have the code sent via SMS to your SIM card. Just pop your SIM into another phone temporarily, or if you have an eSIM, it usually stays active through the reset process so you can receive the text.
How to Avoid This Nightmare Again
Look, nobody wants to do this twice. Once you’ve figured out how to reset passcode on iphone, you should probably set up a "Legacy Contact" or an "Account Recovery Contact."
Go into your Settings, tap your name, then Sign-In & Security. Under Account Recovery, you can add a friend or family member. If you ever get locked out again, Apple can send a recovery code to their device. It doesn't give them access to your data, but it gives them the "key" to let you back into your own house. It's the digital version of leaving a spare key with a neighbor.
Also, for the love of everything tech, check your iCloud backup settings. Settings > [Your Name] > iCloud > iCloud Backup. Make sure that toggle is green. If you're out of storage, pay the extra dollar a month for the 50GB plan. It is the cheapest "insurance" you will ever buy.

Specific Steps for Older Devices
If you happen to be rocking an older model, the button combinations for Recovery Mode change.
- iPhone 7 and 7 Plus: You hold the Side button and Volume Down at the same time.
- iPhone 6s and earlier: You hold the Home button and the Side (or Top) button.
The screen will eventually show the same "Support" or "iTunes" logo. The software side on the computer remains the same regardless of the model.
Actionable Next Steps
- Verify your backup: Go to Settings > [Name] > iCloud and see when your last successful backup occurred. If it was more than 24 hours ago, trigger one manually.
- Update to iOS 17 or 18: Newer versions of iOS have a "Passcode Reset" feature where, for 72 hours after changing your passcode, you can use your old passcode to reset the new one if you forget it. This is a massive safety net.
- Write it down: Not on a Post-it on your monitor, but in a secure physical location or a password manager like Bitwarden or 1Password that you can access from a browser.
- Set up a Recovery Contact: Add a trusted person in your Apple ID settings today so you aren't reliant on SMS codes in an emergency.
