There is no back door password. Lose the password and you'd have to resort to bombastic methods the hackers use, like dictionary, hybrid and brute force attacks to recover the data.
If you use a simple password like just a single characters or a simple word, it could easily be cracked by a dictionary or hybrid crack. On the other hand if you used a crack stifling password that's long and has a mix of alpha-numerics and punctuation you might be beyond the ability of a brute force attack simply because of the time required to crack the password.
Dictionary attack
A simple dictionary attack is by far the fastest way to break into a machine. A dictionary file (a text file full of dictionary words) is loaded into a cracking application, which is run against user accounts located by the application. Because the majority of passwords are often simplistic, running a dictionary attack is often sufficient to to the job.
Hybrid attack
Another well-known form of attack is the hybrid attack. A hybrid attack will add numbers or symbols to the filename to successfully crack a password. Many people change their passwords by simply adding a number to the end of their current password. The pattern usually takes this form: first month password is "cat"; second month password is "cat1"; third month password is "cat2"; and so on.
Brute force attack
A brute force attack is the most comprehensive form of attack, though it may often take a really long time to work depending on the complexity of the password. Some brute force attacks can take a week depending on the complexity of the password.
