GROUP ID: V-253401
RULE ID: SV-253401r991589
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.
Solution
Configure the policy value for
Computer Configuration >> Administrative Templates >> System >> PIN Complexity >> 'Minimum PIN length'
to '6' or greater.
