It won't explode, but Apple does provide a way to wipe your iOS devices clean of all of your personal information remotely. The information in this article applies to all currently supported versions of iOS. How to Erase Data With Find My iPhone To remotely erase the data on your missing iPhone, you'll need to do a little setup first to make it possible. Regularly back up your iPhone data to protect against data loss. Enable Find My iPhone Turn on the Find my iPhone feature on your phone and connect an active iCloud account on your device for Find My iPhone to work. An iCloud account is offered for free from Apple. Tap the Settings app. Tap your Apple ID account (the top item in the Settings app). Tap iCloud. Tap Find My iPhone and switch it ON. If your firmware is pre-iOS 5, follow these instructions to enable Find My iPhone. Remotely Erase Your Missing iPhone When you're sure you won't get your phone back, use the remote erase feature. Once you remote wipe the data on your device, you won't be able to locate it using Find My iPhone. The remote wipe should only be used when you're convinced that you will never get your device back. Open the Find iPhone app from another iOS device such as an iPad or from a computer's web browser. Visit the iCloud.com website and log in to your iCloud account. Select All Devices, then choose the device you want to erase. Select Erase iPhone. Self Destruct After Too Many Failed Passcode Attempts You can set your iPhone to automatically erase its data if the wrong passcode is entered more than 10 times by following these steps. Open the Settings app. Select Touch ID & Passcode or Face ID & Passcode if your iPhone uses Face ID authentication. Enter your passcode if prompted. If you do not have a passcode enabled, turn this on first by selecting Turn Passcode On. Set a passcode of your choice and confirm it. Consider setting a stronger passcode than the default 4-digit one for extra security. Move the Erase Data toggle switch to On/green. Read the warning and tap Enable. Your phone is now set to automatically erase all of its data after 10 failed passcode entry attempts. Use Caution With Erase Data Settings If you have kids or someone else that uses your phone, the Erase Data option could be a problem if you're not careful. Your child might innocently try to guess the code too many times and accidentally erase your iPhone's data. The remote erase feature might make more sense in situations where you have others who regularly use (or play with) your iPhone.
