Is it a matter of not being able to think straight? "Selfie authentication" is no less legitimate for flower delivery than for anything else. And you wouldn't expect to know anything about the company. We don't know anything about most of these companies that hold so much information on us.

Nowadays it's a good rule to not let delivery people photograph you anyway. Anything I order comes by mail and there's no such nonsense. Unsolicited whatever, lemme just take your pic? You can take it back thanks

Some delivery apps like Rappi sometimes require delivery man to take a photo of the order upon delivery. Unfortunately, mail doesn't deliver a hot cheeseburger in 10 minutes.

Picture of the delivery is different than picture of your face.

"Selfie" authentication, or any data gathering, is not legitimate when it comes to unsolicited things. Just because someone knocks on my door with a surprise gift doesn't mean I owe that person anything.
