How to get around facebook login code

[Staceylee477]

Im wanting to change phones from my LG Stylo3 to my little brothers old LG Fortune2. I know how to switch my sim chip. But my problem is when I try to log into Facebook or FB Messenger on the Fortune2 it keeps asking for a login code. A code that I am not getting on FB, text, or email. My Fb is still logged into my Stylo3. How can I make it stop asking me for a code it's not giving me so I can login on the Fortune2?
