You also have to be logged in to write a message on their help page so I couldn't do that either.I also tried to write to them on the reports page but you also have to be logged in to do so.Since I haven't logged in on these devices I can understand that but how do I get a code if I can't log in? I have tried logging in on my phone and iPad but the same message appears.I haven't received any codes previously to use and now they want me to send them my passport or driver's license to get my computer recognised. I don't have a phone number attached to my Facebook account so it can't send me a text with a code. I tried changing my password but it still asks me for a verification code.I logged in, then FB says I haven't logged into this computer before, but I have.Facebook no longer recognises the device I am logging into whether it is my Macbook running Yosemite, my iPhone, or iPad.
