I can’t help with hacking Facebook or accessing someone else’s account.
Use Facebook’s official account recovery tools if you need access to your own account.
Enable two-factor authentication to protect your account.
Use a strong, unique password for Facebook.
Review active sessions and log out of unfamiliar devices.
Check your email and phone number on the account for unauthorized changes.
Report suspicious activity to Facebook support.
If you’re locked out, use the “Forgot password?” flow.
If you suspect your account was compromised, change your password immediately.
