I always just step slightly to the side and politely say I want to opt out of the facial scan and it’s always been smooth for me.

“TSA policy requires that TSOs show each traveler respect and ensure their privacy is protected. Travelers who do not wish to participate in the facial recognition technology process may decline the optional photo, without recourse, in favor of an alternative identity verification process, which does not use facial recognition technology to verify their identity. This action will not take longer and travelers will not lose their place in line for security screening. TSA is committed to protecting traveler privacy, civil rights, civil liberties and ensuring the public’s trust as it seeks to improve the traveler experience through its exploration of identity verification technologies”
