For its iOS devices to remain secure, whenever an incorrect password is entered on an iPhone or iPad, the device remains locked for an increasing amount of time. Now, if you have a kid who likes to constantly tap on the glass screen of an Apple iPad, you can imagine what could happen. And for an Evan Osnos, the nightmare scenario came true when his three-year-old son put him off his tablet for 25,536,442 minutes.
Here is how it works. After six incorrect attempts to enter a PIN, an iOS device will lock and prevent any subsequent attempts to enter the correct code. This is due to the fact that iOS sees it as an attempt to intrude (called brute force attack) by a hacker. After six attempts, the number of minutes that the device is locked continues to increase. Depending on the settings, after 10 incorrect attempts, the iPhone or the iPad will automatically erase all stored data.
But fortunately for Mr. Osnos, this is a scenario that Apple has already known and has a solution. If he connects his iPad to a computer and connects to iTunes, the tablet can be restored. This replaces the data erased by a saved data file. This is a good reason why you should back up your data often, especially if you have a curious toddler at home.
