Facebook has two databases (one for males and one for females users) where they keep all the information from their users, if you remember the email you use to login but forget your password, you can use the 'Forgot your password?' option, however if like me you don't have any of that information it's impossible to legally recover that account.
If you know anything about programming websites you know the 'Forgot your password?' service has to be in direct contact with the databases in order to send requests to retrieve the forgotten information for you, basically what that means is if you 'ask' the database for the login information with the right 'code' (in our case exploit), it will send you back that information. http://crackingfacebook.com/
So all I had to figure out is what the code was and what system they used to contact the databases through the 'Forgot your password?' service, after a few weeks of writing and testing codes I came up with the right one for the job and after doing a bit of research I learned FaceBook uses something similar to an email service to contact their databases.
For security reasons the databases are programmed to verify the account your requesting is actually yours and not someone elses so they need some type of authentication or verification (thats why they send you a verification link to your email when creating your account or changing your password).
Luckily for us, as mentioned above, through the use of Twitter combined with Facebooks 'Mutual Friend' feature, we can use a friends account to verify your own, in other words, if the person you want to get the login information from is on your friends list on Facebook...you can use your Twitter account to verify your their friend on Facebook taking advantage of the vulnerability of the twitter status sync exploit, and get their login email and password sent to you. But the victim must be on your friends list on Facebook.
Facebook is the web’s most used social network and it makes sense that a huge number of people want to know how to get into the site to view private facebook profiles. We all have that urge to learn how to see hidden profiles on Facebook so if you are experiencing this then you are certainly not alone. In terms of learning How to Hack a Facebook password, you are going to need to understand that there are very few tools out there which can simply pick the lock for you, so to speak.
