I struck a big problem yesterday while trying to ready my iPad mini for sale: it wanted my Restrictions PIN. What? I didn’t even know what that was and was pretty sure I’d never set it. Yet there it was: Restrictions ON under the Settings.
I tried a bunch of PIN numbers, such as the one I use for unlocking the device, the different one I use for my iPhone, a couple of rather random guesses.
Then the iPad started warning me that I’d have to wait x minutes before my next attempt.
At that point I went ahead and reformatted the iPad mini, since I was prepping it for sale anyway. That gave me problems too, that were eventually solved by plugging it into the other USB port on my MacBook Pro.
But then I thought:
What about my iPad Air 2? A quick check showed me Restrictions were also in place on that one.
In fear of being forever locked out, or potentially being restricted from things I might want to do, I went searching on Google.
After a lot of hair pulling I finally found Nbalkota’s useful guide, which actually only got me so far, finally finding the
restrictions hash and salt.
Armed with them and after failing the next steps I turned to the iOS Restrictions Passcode Cracker and left it to run, until bingo: it served up a PIN number that worked.
One worrying thing is that the PIN that was served up is a sequence known to me from other uses. That tells me I’m definitely the one who put it in there, even though I could find no note of it in 1Password or Evernote. I guess I decided to set a PIN so no-one else could casually pick up my iPad and lock me out of various activities for a joke or other reason.
Check your iOS devices: have you set a Restrictions PIN? Do you know what it is? Should you set one? How will you record it?
