But the problem is that he doesn't have any 2 factor authentication methods setup! That means he cannot reset the password or add a 2 factor authentication method.
He has access to the Facebook account from Facebook app installed on an Android phone he no longer uses. Please note that he has access to the linked phone number. But since 2 factor is enabled through "protect", it is not enough to do anything!
I have found absolute no way to contact Facebook for this problem. Can anyone help with this?
