Use a PIN Instead Of a Password to Log In to Windows 10
Did you know you can log into Windows with a four-digit PIN instead of a password? Maybe it’s not as secure as logging in with a 14-character password, but it’s much better than nothing at all. It’s quicker and easier to type in a 4-digit PIN and easier to remember. So, if you’d like log into Windows 10 with a four-digit PIN, instead of a password, just follow the instructions below:
Click Start —> Settings (you can also access setting by pressing Windows key + i )
Click on Accounts then click Sign-in Options (See below).
Under PIN click “Add” (I’ve already added a PIN so my option says “Change “instead of Add). When you click Add under PIN you’ll be prompted to verify your Windows Password.
Enter a 4-digit PIN (see image below), verify it, then click Finish. The next time you restart Windows 8.x you’ll be prompted to enter your PIN. If you ever forget your PIN, you will be redirect to the normal password prompt and you can log in by typing in your password.
And that’s it. Next time you log in to Windows, you can use your 4-digit PIN instead of your password. But don’t forget your password — you may need it again after a major update or if you reset your computer.
