If you choose to link your Microsoft live account to your Windows 10 user profile, you will automatically apply a password lock to the screen.
The password that you will enter to unlock your system would be the same password you use to sign in to your live account.
If entering the password to your live account every single time annoys every time just to you unlock your system, then you can set an alternative password for a Windows 10 live account and use this password to sign in to your system.
This alternative password for a Windows 10 was a part of Windows 8/8.1 as well and is a built-in feature of Windows 10. You can set a PIN Code or a picture password and use that to sign in instead of entering your live account’s password every time.
To set up either a PIN or a picture password, follow below mentioned easy steps.
First, click “Start” menu and open the Settings app.
Go to the Accounts.
Select the ‘Sign-in options’ tab. Choose one of the two alternative password options; PIN or Picture Password.
If you have more than one system that has Windows 10, you can set a different PIN or picture password for each one of those.
This specific type of password does not synchronize through devices. It is just another layer of security added because by default the PIN is only four digits long and can be memorized easily.
If you are entering the same one on every machine you have, it is bound to be noticed. Alternatively, you can change it so that the PIN includes alphabets as well. It will spread the length of your PIN beyond the default 4 digits
The settings screen for setting up the PIN says you can use it to sign in to apps and services. This PIN will only work on the PC it is configured for. One plus point of using a PIN is that once you enter it, you do not have to tap the Enter key.
This applies only to four-digit PINs and not for alphanumeric ones. It is a small advantage but you would be amazed at how quickly you will get used to it.
