The answer? 25 million!
A two-year-old boy in Shanghai reportedly shut down his mom’s iPhone by repeatedly entering the wrong passcode. The mom said her son was allowed to use the phone to watch ‘educational videos’. But she returned home to find that he had entered the wrong password so many times that it locked for 25 million minutes.
The same thing could happen to your phone if someone spent long enough typing in the wrong password. Apple’s security system locks the phone in increasing increments of time when the wrong password is entered, starting with a small amount and then quickly growing with each incorrect attempt.
Of course, locking your phone like this isn’t a total nightmare, because all you need to do is erase your phone data and do a factory reset.
