Windows 11 must be configured to require a minimum pin length of six characters or greater.


Overview

Finding ID Version Rule ID IA Controls Severity
V-253401 WN11-CC-000260 SV-253401r829287_rule Medium
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.
