I reopened my account to use as a backup, enabled 2FA by scanning the QR code.
But it seems no matter how many times I log out an back in I'm not being asked for a code.
*scratches head*
If I understand your post correctly,
2FA is for changing the payout address, if set up, not for logging in.
Lol, either way 2FA is better served against login IMHO.
