Yes, I know. I do opt-out of 2FA in those cases where I won't have access to my computer during the weekend when I have to perform the login.
I was hoping that
@nooby_mcnoob 's reply implied that it would be possible to do the 2FA verification purely on the mobile phone. In that case it would work for me when I have no access to the computer. But alas, that's not the case. I don't want to give the computer access to the internet through VNC and try to do it remotely, which is why I disable 2FA on cases when I have no access to it.
Of course, once I get back home I re-enable 2FA again as I do like the extra "sense of security" that 2FA offers.
