PIN length changed from 4 to 6 after upgrading to Management of Native Encryption 4.1.1

Technical Articles ID: KB89339
Last Modified: 2022-10-03 06:48:58 Etc/GMT

Environment

Management of Native Encryption 4.1.1

Microsoft Windows 10 version 1703 (Creators Update) and later
Microsoft Windows BitLocker

For details of MNE-supported environments, see KB79375 - Supported platforms for Management of Native Encryption.

Problem

After you upgrade or install MNE 4.1.1, the ePO administrator can no longer select the expected BitLocker PIN length of four (4). This PIN length is selected in the MNE Authentication Settings policy.

After a new installation or upgrade of MNE 4.1.1 to Windows 10 version 1703, the new minimum PIN length is six (6).

The MNE 4.1.0 Product Guide states the following for BitLocker Product Settings policy options:

Minimum PIN length (4–20) - Enter the minimum PIN length from 4 to 20 that you would like to set for the PIN number

Cause

The minimum new PIN length was introduced into the Microsoft Windows 10 version 1703 release for BitLocker. This update led to a change in MNE 4.1.1 and later to support Windows 10 version 1703, to allow the MNE policy to support a fresh activation on this version of Windows and later.

Solution

On Microsoft Windows 10 version 1703 or later, the minimum BitLocker PIN length policy requirement is 6.
