Ask your child for his Facebook password and the email address your child uses to access his Facebook account.
Log in to your child’s Facebook account using the credentials provided to you by your teen. Once you have access to the account, click the “settings” button in the upper right corner of the page and select “account settings” from the dropdown menu.
Click the “edit” link to the right of “password.” Enter the current password in the top box. Create a new and different password in the middle and bottom boxes. This should be a password that your child does not know. Click “save changes.”
Click the “edit” link to the right of “email.” Click “add another email” and enter your own email address in this box. Enter the Facebook password to save the new settings and click “save changes.” Find the confirmation email Facebook sends you and confirm your email address. This will enable you to receive notification emails from Facebook based on account activity.
Click the “security” tab in the left sidebar. Click “edit” to the right of “login notifications.” Place a checkmark in the “email” box to receive emails notifying you of a login to the account by an unidentified browser. Click “save changes.” Click “edit” to the right of “login approvals.” Place a checkmark in the box to require a security code to access the Facebook account from unknown browsers. Click “save changes” – this will make it impossible for your child to log in to the account from an unknown browser.
Contact Facebook if your child is under 13 to file a report of an underage child. Provide the URL of the child’s timeline, the name of the child, the email address connected with the account, the age of the child and your relationship with the child. Upon receiving and confirming the information, Facebook will delete the account.
