I think behind the scenes they keep log of some sort of fraud risk, e.g. geoip different from billing country, suddenly a new operating system, vnc/teamviewer running would probably flag your account (even for benign purposes, e.g. you can get your money back or purchase cancelled if that info can prove your transaction was actually unauthorized). I worked on a ecommerce where the previous developers implemented a rudimentary "score" system like that so that suspicious orders would be put in queue for phone verification (this was pre gdpr)
