Facebook is very heavy into user login authentication and if they don’t think the person logging into your account is you they will verify with typical 2FA, pictures of your friends, and requesting photo ID (I could be getting the ID request confused with account recovery). I don’t know what the roadmap would look like with a coordinated leak of Facebook accounts but FB’s login security would prevent a lot of shenanigans.
