It would be very helpful/more efficient if you offered the 2FA to be sent to the user account email address on file or offer a SMS/text message option. We had some issues with some of our users not being able to set-up the 2FA through a 3rd part app so we had to turn off 2FA for their account so they could acces Printavo. I think the 2FA is a good idea, but there should be more options for the passcode that are less cumbersome to find where it is being sent.
