How to Extend the PIN Length in Windows 10 & 11
Windows Hello enables users to sign into Windows 11/10 accounts with PINs. That feature restricts users to four-character PINs by default. There isn’t an option available within the Change your PIN box to set a longer PIN that includes more than four characters.
So, it doesn’t seem users can set longer, more secure PINs for signing in to Windows. However, there are two ways to set a new minimum PIN length for the Hello PIN sign-in method. This is how you’re able to extend the PIN length in Windows 10 and 11.

Extend Your Windows PIN to Make It More Secure
Extending the minimum PIN length for logging in to Windows with one of the methods above is a good security measure. The longer your Windows Hello PIN is, the more secure your PC will be. However, an overly long PIN will be harder to remember. So, don’t make your PIN too long!
Windows Hello also enables users to set alternative biometric authentication. Fingerprint or retina authentication types are more advanced Windows Hello features than PINs. However, you’ll need a PC that supports such biometric security features to enable them.
