How can I lock my sister out of beloved Facebook account?
<|assistant|>
It is unlikely that you will be able to permanently lock your sister out of your Facebook account. However, there may be some options that you can explore. You may want to reset your password and then notify your sister that she is no longer allowed to use the account. You can also report your sister's activity to Facebook as unauthorized. Finally, you can disable your account, which will prevent anyone from accessing it until you log back in.
