How to Unlock iPhone 17/16/15 Passcode Without Computer [Tutorial]

Getting locked out of your device is a frustrating and stressful experience. While connecting to a computer is a common solution, what if you don't have one handy? This comprehensive guide provides four quick ways to unlock your iPhone passcode without a computer. However, you should note that most of these methods will erase all the data and settings on the iPhone. Whether you remember your Apple ID or have Siri enabled, follow the detailed steps to unlock your iPhone passcode without a computer.

Reset your iPhone from the Lock Screen (iOS 15.2 or Later)

If your iPhone runs iOS 15.2 or later, you can use the new Apple feature called "Erase iPhone" on the Lock Screen. This is the most straightforward method to unlock an iPhone passcode without a computer if it's available. However, you should connect your iPhone to the network through Wi-Fi/cellular and know your Apple ID and password. Then, you can follow the steps below to unlock the iPhone Passcode without a computer from the lock screen:

Step 1On your iPhone's Lock Screen, repeatedly enter the wrong passcode until you see the "iPhone Unavailable" or "Security Lockout" message.

Step 2Tap the "Erase iPhone" button in the bottom right corner of the screen. Tap it again to confirm your intention. On iOS 17 and above, you should tap the "iPhone Reset" button.

Step 3Enter your Apple ID password to sign out and disable Activation Lock. Tap the "Erase iPhone" button to erase all content and settings. Once the process is complete, your iPhone will restart as if it were new. You can set it up from scratch or restore from an iCloud backup.

Unlock iPhone Passcode via Find My iPhone on Another Device

If your iPhone is running an older iOS version or the Lock Screen method fails, you can try using Apple's Find My service on another iPhone or iPad to unlock the iPhone Password without a computer. In this method, you also need to enter the Apple ID and password of your locked iPhone, and the Find My function should be enabled before. Then, check the steps to unlock a disabled iPhone without a computer.

Step 1Open the "Find My" app on another iPhone or iPad and log in with the same Apple ID that is used on your locked iPhone.

Step 2Tap the "Devices" button at the bottom and select your locked iPhone from the list. Swipe up on the device info card and tap the "Erase This Device" button.

Step 3Follow the on-screen instructions to confirm the erase process. This will remotely wipe your iPhone, unlock the iPhone password without a computer, and erase all data.

Use Online iCloud to Unlock iPhone Passcode without a Computer

Besides using another iPhone or iPad to unlock iPhone passcode without a computer, you can also use the Find My function on a browser on any device! If you have the iCloud Apple ID and Passcode, you can use iCloud online without any device limitations. No need to install the Find My app, you can use any mobile or tablet to unlock the iPhone Passcode. It's definitely a powerful tool that gives you control over your devices from anywhere, as long as you have an internet connection and your login credentials.

Step 1Open a browser on any mobile or tablet and go to the official iCloud website (iCloud.com). Sign in with your Apple ID and password, and then tap the "Find My" button.

Step 2Click the "All Devices" list at the top and select your locked iPhone. After that, click the "Erase iPhone" button and confirm your choice. Once erased, you can unlock the iPhone passcode and set up your iPhone again. You can even change the iPhone lock screen password now.

Unlock iPhone Passcode with Siri and Clock (Older iOS Versions Only)

This Siri shortcut exploit was patched by Apple many years ago (around iOS 10/11). It only works on very old iOS devices running iOS 8 to iOS 10.1. The success rate of this method to unlock an iPhone passcode without a computer is very low, but you can try it since it will not erase the settings and data on the locked iPhone. Follow the steps to unlock iPhone with Siri:

Step 1Press and hold the "Home" button to activate Siri from the lock screen. Then, Ask Siri to "Open the Clock". Once the Clock app opens, tap on the "Add" button to add a new clock.

Step 2Type anything in the text field to name the new clock, then double-tap the text to bring up the editing menu. Tap the "Select All" and "Share..." buttons from the pop-up menu.

Step 3On the "Share" sheet, you can try to tap on the "Message" app. If successful, this might give you access to the Messages app, from which you could try to access other phone parts. This process was never guaranteed and is now obsolete.
