EPIC SECURITY FAIL! This app requires a 3rd party QR code scanner called ZXing Barcode Scanner. As instructed by Google  I get the App from Play store. Then scan the QR code shown on Google 2-factor setup. I clicked the screen in ZXing QR scanner... WHAMO! ZXing barcode """"""""""""""""app"""""""""""""""" takes me to a scam web site (LuxQuiz) offering me a free iPhone 6s! But only after I give them my credit card info for the $1.99 shipping fee! Gee  thanks Google for partnering up with such a solid 3rd party. UN_BELIEVABLE!!! Get it together Google.""
