If you have a long password for your Windows computer, then every time you login you are wasting some time in typing it. If you want to login to your computer quickly then there are two methods: first one is to create a picture password and the other is to create a PIN. Windows 8 provides an alternative login mechanism to login to your computer by using a 4 digit code known as PIN.
Here are the steps to create a 4 digit number PIN in Windows 8:
1) Go to: Charms bar –> Settings –> Change PC Settings –> Users
2) Click on “Create a PIN”.
3) Enter your current password.
4) Then, enter any 4-digit number as per your choice and then, confirm it.
5) Click on “Finish”.
You have successfully created a PIN for logging in to your Windows 8 computer.
