Windows 10 must be configured to require a minimum pin length of six characters or greater.
An XCCDF Rule
Description
Windows allows the use of PINs as well as biometrics for authentication without sending a password to a network or website where it could be compromised. Longer minimum PIN lengths increase the available combinations an attacker would have to attempt. Shorter minimum length significantly reduces the strength.
