Have a Facebook account for several years. Have a new email address and never changed it. On my phone I forgot my password and I opened a new Facebook account with my new email. Here's the problem, I went back on my computer and my old Facebook was still signed on so I tried to change the email but says The email is already on the other Facebook and I can't remember my password on the new Facebook.
When I try to change my password on my old Facebook the code required to change it goes to my old email which I can not get in to get the code. What can I do to have my new email into my old Facebook.
