When you forget the password of your email, facebook or Twitter account you simply click "Forget my Password". But what about your iPhone? What if you set a ‘Restrictions Passcode’ a long time ago and now you can’t remember the digits?You’ve got a couple of options. For starters, you could restore your iPhone as a new device through iTunes. You can’t restore from a previous backup, because your passcode is saved in that file
Your other option isn’t quite so painful. All you need is about 5 minutes and iPhone Backup Extractor for Mac OS X, which you can
get here. This guide is specifically for Mac OS X users. But if you meet the criteria and could really use some help recovering your iPhone passcode, dig in!
Step 1: Once you’ve download the free app, iPhone Backup Extractor, open it up and let it extract itself. You will then want to click ‘Read Backups’. 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. This is what your Passcode is, enter it in your iDevice, and thank Simon Blog for sharing this little tidbit with us.
It is important to note that jailbroken users, can also locate their passcode via
SSH Bellow. All you have to do is navigate to ‘
var/mobile/Library/Preferences’.

How to SSH iPhone:
Many users asked me about SSH, so I prepared this simple guide for them. At the begining What is SSH ? and why we do it?. SSH (Secure Shell) allows you to exchange data between two networked devices, using a secure channel. A jailbroken iPhone has the ability to connect with your computer via SSH, giving you read and write access to your iDevice’s hard drive.
Why we do SSH? You can repair damaged files, install games that aren’t in the App Store, and even turn your iDevice into a portable hard drive. I know it all sounds complicated, but we use applications to make the process as easy as browsing a folder on your computer. This is my quick and easy guide to SSH into your iPhone….
For beginners, your device MUST be jailbroken. You MUST also have an active Wi-Fi connection on both your iDevice and your computer.
Step 1: Download Cyberduck for Mac or for Windows.
Step 2: In your jailbroken iDevice, open ‘Cydia’ and do a search for ‘OpenSSH’. Go ahead and install it, and jump back on your computer.
Step 3: Open the Cyberduck application we downloaded earlier and click the ‘Open Connection’ button.
Step 4: In the server field you are going to type your iDevice’s IP address. This can be found by launching your ‘Settings’, selecting ‘Wi-Fi’, and selecting the blue arrow next to your wireless network. You should now see your IP address.
Step 5: Select the ‘SFTP’ option in the drop down menu above where you just typed in your IP address.
Step 6: In the Username field type in ‘root’. In the Password field type ‘alpine’. Click connect! You are now looking at the file system underneath Apple’s iOS!
Note: The first SSH may take a bit, after that it should be fine. If you get an ‘Unknown Host’ message, just ignore it and click ‘Allow’.
