Two-factor authentication prevents hackers from taking over Facebook accounts.

Is it true that two-factor authentication prevents hackers from taking over Facebook accounts?

Partly. Evidence is mixed and only partial: one source says 2FA enhances credential security on platforms such as Facebook and another says 2FA significantly improves password-based authentication security, while other sources document 2FA bypasses such as phishing, SIM-swap and third-party breaches, and one case study describes a Facebook account being hacked. None of the sources settles whether 2FA actually prevents hackers from taking over Facebook accounts.
