IPhone's scary feature: erase all data when entering the wrong password too many times

For many people, setting up a mode for iPhone to manually delete all data if entering the wrong password too many times is really scary. Who knows if you will ever forget your password? But there is a very compelling reason why you should enable this feature.

Located very deep in the iPhone settings is the option to delete all phone data after 10 times of entering a wrong password. Most users turn off this feature for a very simple reason: if someone tries to open the phone you can't, you will lose all data.

John Gruber of Daring Fireball said it was not that simple. 'After 5 attempts, iOS will require a 1 minute break before entering again. In the meantime, you can only call emergency 911. After the 6th time, the waiting time increases to 5 minutes. After the 7th time is 15 minutes. Just like that, it took more than 3 hours to enter 10 times wrong. '

In fact, ordinary people won't try to open your phone to that extent

In theory it sounds scary but a child or friend or relative will not be able to accidentally delete your data. Conversely, this feature can protect phone data from bad guys, try to unlock the phone.
