Typing in my Windows Live account password every time I turn on Windows 8 lows me down when I just want to quickly access an app. Microsoft includes a logon PIN feature but it is not exposed to users when an account created. Although this reduces the physical security of your computer I like to use a logon PIN so I can quickly log in, and best of all, with just one hand.
Select Users and then Create a PIN.
Enter your current password and hit OK.
Enter a four digit PIN and hit Finish.
Your PIN is now configured. The next time you see the logon screen just key in your PIN. As soon as your four digits are entered you will be logged in, no need to hit Enter.
