A list of your previous backups should now populate. Just select the backup that you want to extract the passcode from. Step 2: You should now be looking at a list of apps that have been backed up. Scroll all the way to the bottom and click ‘iOS Files’, and then ‘Extract’. I recommend extracting it to your desktop so you can find it easily. Step 3: Extraction will take a minute. Once completed, open the folder it created called ‘iOS Files’. Look for the file named ‘com.apple.springboard.plist’, and open it up. Step 4: As you scroll down this list of properties, you should see a key titled ‘SBParentalControlsPin’ and to the right of it a value.
