How can I lock my sister out of beloved Facebook account?
<|assistant|>
To lock your sister out of your Facebook account, you will need to call Facebook customer support or go into the settings of your account and enable the two-step authentication process. Once you have completed this process, your sister will be required to enter a special code sent to her mobile phone in order to access your account. Without this code, she will be unable to access your account.
