Hi
The site's two factor authentication setup is broken. I tried to set up 2 FA, but the box which holds the QR code is blank. There's no QR code.
Please fix it.
This happens more often, under the white box you can see a code which looks something like this "IZCEW33INM4WU3LW"
With that code you can add it manually to your 2-factor authentication app.
