I'm sure people would complain about most of those on privacy and/or antitrust grounds. > "You're logging in from a new device. Please check your email for a verification code." This site is keeping track of all the devices I use, which is not necessary to provide their service. > "You're logging in from an unusual location. Please answer your security questions to continue." They are also tracking my location, which is not necessary to provide their service. > "We've sent you a text message with a code which is valid for the next 10 minutes." They make me provide a phone number, which is not necessary to provide their service. > "Press OK on the 23andme app to continue." They have a perfectly good web site, yet they require me to use their proprietary app (which requires me to have an Apple or Android phone or tablet). This is not necessary to provide their service. They are probably getting paid by Apple and Google to try to force people to have they devices.
