Microsoft has introduced a change in Windows 11 versions 24H2 and 25H2 where FIDO2 security keys may prompt users to enter a PIN during sign-in after installing updates released since the September 2025 preview update. This change is intended to comply with WebAuthn specifications, which require user verification when set to 'preferred'. The feature began rolling out with the KB5065789 preview update and was fully deployed with the November KB5068861 update.
