Single post in Two-Factor Authentication

I won't be using it because I don't have a QR scanner and I don't really know how I'd set this up without having to trust some random QR app. Also, chrome automatically saves my login for my email so I auto-login to every site and if not it's saved to the webpage so I don't really have a use for this aside from making it more difficult to hack my account but it's more difficult for me to even login too so I would just get annoyed with it .-. This has no impact on me whatsoever.
