Windows 10 offers users several ways to login, for example regular password, Windows Hello, PIN code, etc. By logging in with the PIN code, which was first introduced in Windows 8, you can easily enter your account. Authentication with a PIN is easy and secure because you don’t have to enter a real password (usually a Microsoft account password) every time you unlock or turn on the system. Even if your PIN is compromised, your other devices using the same Microsoft account will not be compromised.

In addition, you will not be able to protect your system with a simple PIN that only uses numbers. Fortunately, Windows allows you to add complex requirements such as minimum length, special characters, letters, etc. D. to the PIN code to make it more efficient.
