There could be situations when you need to hack your own Mac and situations when you have trouble remembering your login password. Do not freak out when this happens - it is not a big deal. Learning how to reset or bypass Mac OS X password will be a great advantage because not only are you able to have access back into your Mac, but also keep your Mac better protected as bypassing the login password is really easy.
As a good practice, we recommend refreshing your login password regularly. There are a couple of ways to do it.
Open the Apple Menu located on the upper-right corner of the screen. Open "System Preferences" and click on "Users & Groups".
Type in your username and password to "Unlock" the Users & Groups preferences.
In the left panel, highlight your username. Click "Reset Password".
Key in your new password and verify it. For future reference, it is highly recommended that you place a hint. To finish the process, click the "Change Password" button.
Now, while refreshing your password may be good practice, it is tiresome to remember your password. At one point or another, many of us just forget our passwords and there is no way for you to enter your account on your Mac.
Do not worry about that. Here are some ways you can bypass the Mac OS X password and regain access to your computer.
Pop in the Mac OS X installer CD and hold the "C" button while you restart your Mac. Wait until the Apple logo and the "Mac OS X Utilities" window appear. On the menu bar at the top of the screen, click "Utilities".
Click "Terminal" and type "resetpassword" in the prompt. Press the "Enter" button on your keyboard.
Select the specific "Volume Hard Drive" in the top section of the window. Select the "User Account" that needs its password to be reset and enter the new password. Verify the password and click the "Save" button.
Click "OK" when the prompt asks you to verify your actions.
Once you get into your desktop, restart your Mac to boot it back to normal and log in using your new password.
Method Two: Reset the Password in Single User Mode
Not all of us keep the installer CD or know where we have kept it. Therefore, this method will come in handy. It will involve some command-line footwork, but do not let that scare you away.
Restart your Mac while holding the "CMD" and "S" buttons. Your Mac will boot itself into the Single User Mode.
Type the following commands and press "Enter" on your keyboard after each line and wait until it prompts you to key in the next line.

As you can see, it is really easy to hack into your own Mac. Therefore, it is important for you to protect it from malicious intent. To add protection to your device, you can set up a firmware password. By having this layer of protection, an unauthorised third party will not be able to reset your machine even in single user mode.
Here is how to go about it.
Pop in the Mac OS X Installer CD and wait for it to boot. You will soon be able to see the "OS X ""Utilities" window.
Open the "Utilities" menu and click "Firmware Password Utility" to set a firmware password.

Open the "FileVault" tab and click "Turn On FileVault". Your disk is now encrypted.
