They're still used for instant login on multiplatform services like Steam or Discord. A device that's not logged in will show a QR code next to the login prompt, and scanning it with a logged in device will show a prompt to allow the other device to log in to your account without needing to enter a username or password.

Other than that, I only see them at restaurants to open their menus in a web browser.
