This 'super' iPhone security mode will ensure that the data in the iPhone cannot be exposed

This is only advisable if you regularly back up data on your iPhone or iPad and can get your information back without any problems. This is the ultimate security feature that makes it difficult to reveal your personal data even if your iPhone is lost.

Step 1: Go to settings > Face ID / Touch ID & Passcode

Step 2: Enter your passcode and then scroll to the bottom of the page. Slide the button next to Clear data to the On position.

Once enabled, if someone mistypes your device's passcode 10 times, it will automatically factory reset. This process doesn't just take a few minutes. After a few mistypes, your phone or tablet sets a time limit before someone can try to re-enter your passcode.

It takes up to 10 unsuccessful attempts in 1 hour and 36 minutes for the iPhone to return to factory settings by itself. So your iPhone will never be able to expose data even if it is taken over by crooks.
