Thanks for responding but my number is registered for login codes but still not receiving, tried to log in the messenger, immediately code came but took long to connect and then connection interrupted.After that tried several time but of no use.
I'm having the same problem I have the two-factor authentication set up on there and I managed to logout of Facebook on my phone which is registered to Facebook I don't have an email registered to Facebook. When I ask it to send me a code it does not send me a code. I have googled it I have went to The help center on Facebook and I cannot figure it out for nothing.
