I know it.
But I never see this code when I first time set up google 2FA.
I have few maybe several 2FA and always I saw removing code. But on this ICO I dont saw this code. Or I am blind. Send me pictures in some free times if someone set up 2FA and know where was this removing code.
I can still make disable my 2FA and enable again and write code manually on paper. But need know where its the code
A QR code is basically a substitute for letters and numbers. I too shared your concern. What I did was scan the QR code with a scanning app, then wrote down what it revealed, just in case. That was before reading one of the previous posts. I don't believe it's necessary, just contact support if you lose your phone.
