If yes, then think it twice after reading this post

If you have protected your laptop with password that doesn’t mean that your laptop or system is safe. You have just locked the pc/Laptop not the application or data within it. However when a thief steals your laptop its not that much difficult for him to hack your password or even if an administrator forgets the password he can easily break it. Passwords are good to have, but will not stop a thief from accessing the device, only slow them down a bit. Here is a quick run through of some common techniques for getting around the passwords for different platforms:

Windows Xp & Vista/7

Windows can be cracked using several available tools

OPHCRACK - Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms. It comes with a LiveCD version which automates the retrieval, decryption, and cracking of passwords from a Windows system. The latest version uses a new faster technique using rainbow tables and can crack 99.99% of alphanumeric passwords of up to 14 characters in usually a few seconds, and at most a few minutes. The software works with older versions of Windows as well.

These are just a few techniques to get rid of password protected Laptops. One thing you must kept in mind while setting up password that is you password must be a Phrase not a word because 14 character passwords can be cracked in a matter of minutes. Most IT administrators require a password of 8 characters, this is not sufficient. It is better to devise a phrase instead of just a word.


If you have sensitive information on your system, it is important to ensure that the data is encrypted, many operating systems have this built-in and there is also free encryption tools such as TrueCrypt that provide excellent encryption, so even if your password protected laptop is cracked, your data is still secure, just make sure you use a different password for your encrypted drive.
