In order to connect to Amazon using Firefox on my PC, I am required to scan a QR code with my phone and then, presumably, connect via Firefox or Amazon apps (instructions woefully unclear). It NEVER works. It's no big deal, but it is annoying, particularly since I want to use Firefox as my default browser. I can always connect via Google or Edge. For those of us who aren't tech savvy, why don't you add standard two-factor authentication or Windows Hello as an option?
