Facebook Login - Security Check

Does anybody know how to get around a security check when logging into FB? I have an account which I used to login from a certain IP address. Now that IP address changed and I can't get around the security checkpoint from FB.
(PS: uploading ID does not work)

It gives 2-3 options in such a case.

yes.
1. login with old IP address (which I don't have access anymore)
2. upload ID (which they don't accept as the account is not real)
3. provide birthday (which I don't have as the profile was set to private when we set it up)

do you have any ideas how to solve this?
