Southwest Rapid Rewards - Changes to Airport Kiosks

Just got an notice when printing my boarding passes:

"Changes to Airport Kiosks

Due to some recent regulatory requirements, we had to make a few changes to the way we retrieve reservations on our airport kiosks.

If you normally swipe a credit card or driver's license to access the kiosk, you will now need to answer a few security questions before we can retrieve your flight information.
Don't forget you can also access the kiosk to look up a reservation by swiping your Rapid Rewards card or by manually entering your confirmation number or Rapid Rewards number. If you choose one of these options, your experience will be the same as it has always been."

Anyone know what the extra steps are?

ISTR I had to enter my birthdate and gender last time I used one of the kiosks.

The same here, but I've been noticing this for at least a month...maybe longer?

same here.

Is there a difference when using southwest kiosk versus shared airport kiosk? IE ones at DAL vs LAS

That's been going on for a while now, at least 3 months.
