How can I get back into my facebook account?

You might have to complete a security check by detecting photos of your friends and placing the right name on each picture, you may have to enter a mobile phone number to confirm your identity, they may make you show a license or other form of photo identification, or try logging in from a different location that you have logged in from before. If you aren't logging in the location you typically are, they might think someone is trying to hack you. If someone is actually trying to hack you, they will inform you of suspicious activity and may ask you to change your password. If Facebook believes you are sending friend requests to users you do not know, they may give you a warning and temporary block you from sending friend requests.

Log out and log back in and Facebook will probably give you one of these options I have listed above. Trust me, I have gone through this a multitude of times.

Good luck.
