Please2 guys do not try to use 2FA as its not working and then you will not be able to log in back, you will need to open a ticket with support, i think they should unable that option as it will make people not to be able to log in
No problems here with 2FA, just use an android device / Google Authenticator app / setup account / scan QR code
I used 2FA for other things...its working for you but not for me as when I scan the bar code it gives me an error and then I log out and will not let me log in....anyway I have send a ticket
