This policy setting determines whether the account name of the last user to log on to the client computers in your organization will be displayed in each computer's respective Windows logon screen. Enable this policy setting to prevent intruders from collecting account names visually from the screens of desktop or laptop computers in your organization. The recommended state for this setting is: Enabled. Rationale: An attacker with access to the console (for example, someone with physical access or someone who is able to connect to the server through Remote Desktop Services) could view the name of the last user who logged on to the server. The attacker could then try to guess the password, use a dictionary, or use a brute-force attack to try and log on. Impact: The name of the last user to successfully log on will not be displayed in the Windows logon screen.
To establish the recommended configuration, set the following Device Configuration Policy to Enabled: To access the Device Configuration Policy from the Intune Home page: Click Devices Click Configuration profiles Click Create profile Select the platform (Windows 10 and later) Select the profile (Custom) Enter a Name Click Add Enter the Details below Name: <Enter name> Description: <Enter Description> OMA-URI: ./Device/Vendor/MSFT/Policy/Config/LocalPoliciesSecurityOptions/InteractiveLogon_DoNotDisplayLastSignedIn Data type: Integer Value: 1 Select Save Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.) Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy. Default Value: Disabled. (The name of the last user to log on is displayed in the Windows logon screen.)
