The deadline has changed to May 3, 2023 to update your driver’s license to be homeland security compliant in order to fly, enter a military base or federal building. If your driver’s license is up for renewal between now and May 3, 2023 you may update your license at that time. If you license doesn’t expire until after this date you will need to update your license. A passport does work (and of course the passport card that the federal government is offering as an option with passport renewal).
