HOW TO CREATE A PICTURE PASSWORD IN WINDOWS 8


Let`s see how to create and use picture password in windows 8, it`s totally a new feature in windows 8 which earlier versions don`t have.With this new feature we can log-in to PC without the use of a keyboard, may be this feature mainly targets tabs and some touchscreen PCs though it is useful to normal PCs.However it is one convenient way i found to log-in, so far.

Let`s Start....
As depicted below, access the settings

Change PC settings

click on "create a picture password" as depicted below

Then it will ask you for your PC`s password->enter password

Then it will ask you to choose a picture as depicted below

select a picture from your PC

You can adjust the picture if you want to..and click on "use this picture"

This part of the process is crucial. We create the password using Gestures like combination of circles,Straight lines and Taps, and we can use a maximum of three gestures,lets start creating.....

Whatever we draw here it will remember the POSITION,SIZE,DIRECTION & ORDER, so draw them in a Pattern which you can remember(who don`t have a touchscreen,those can use their mouse to draw these gestures). 

Note that you can use combination of circles,straight lines & taps (or) you can use any only one of these things as three gestures so make your choice...(That means for example one can use three taps(or) three circles(or)three straight lines(or)a circle & a tap & a straight line...like that. 

Below i used two taps and one circle.
1 st Gesture- A Tap
2nd Gesture-A Tap
3rd Gesture- A clockwise circle

Repeat the three gestures to complete the process(or) You cat startover again by clicking the "start again" button on the bottom left side.

After that click on "Finish" button.

There you are...Just test it by locking(windows key+L) and unlocking by gestures.

If you feel it uncomfortable you can switch back to the traditional method of unlocking by entering the password by just clicking on the button "Switch to password" as depicted above.
