How to use Picture passwords in Windows 8.

Picture Passwords are one of the most innovative new features provided in Windows 8 that enables you to Logon by touching or clicking specific parts of a picture to authenticate.
Any picture that resides in your picture  library, or on your hard drive's other location can be used as a reference to help you remember where the three parts of your picture password are located. Basic gestures such as dragging your mouse along a specific part of the picture can also be used as your password.
Steps to configure Picture Password:

• Click or touch the metro Control Panel tile from your start menu.
• Select Users >> Create a picture password.
  
  • Enter your current password to authenticate and hit OK.

• Now, you need to choose a unique picture to make it you password. So now, Click on Choose Picture. This picture will consist of your reference points to use them as your password.
  

• You can choose any picture from your Picture Library of from any other location on your hard drive. After choosing picture, confirm the picture with Use This Picture button.

• Now to make reference point passwords on the selected pic, Touch and swipe or click and drag in three points on the picture.

•  Repeat the points by Touch and swipe or click and drag on the picture you selected to confirm your password.
• Your picture password is now configured. Hit OK.

• When you Logon next time, you will see a picture to provide your password. Just Touch and swipe or click and drag the points that you have previously configured as your password.

 That's all done.
