Use Login Window Mode for 802.1X authentication to a network

You can authenticate to a network from the login window when your Mac is set up with a compatible Directory Service and configured to use this mode with MDM.

To use Login Window Mode for 802.1X authentication on your Mac, here's what you need:

  • A bind to an Active Directory (AD) or Open Directory (OD) server

  • A network configuration profile installed that enables Login Window Mode for the desired Ethernet interface or Wi-Fi network

To change the login display to always ask for the user name and password, follow these steps:

  1. Choose Apple () menu > System Preferences, then click Users & Groups.

  2. In the sidebar, click Login Options. You might need to click the lock iconSystem preferences lock icon in the lower-left corner and authenticate before you can make changes.

  3. Next to “Display login window as,” select “Name and password.”
