Log in without faffing about

I was thinking its way to easy to log into Minecraft, I only had to scan a QR Code type in an 8 digit verification code, then sign into my email type another verification code and then cross my fingers and hope it works (which itdoesnt 9 times out of 10).... far to easy, next you'll just have "USERNAME" & "PASSWORD". Why not have a quadruple verification system. The link should go to a Mojang site that you then have to set up an account for and then verify that account on you smart TV, then the Smart TV could sent a QR Code to your phone that you then have to scan with a different phone that links to the Minecraft main servers and you have to type the URL of the last World you remember logging into and then finally there's just a normal "Username", "password" bit on the actual game.
