@Needtobestrong In all the responses it is revealed that there is no scope for absolute privacy. These are the trendy days hacking biggies accounts. If family members are not techies, then there is a semblance of privacy. If some one is bent upon spying can have access to any account easily employing a professional hacker read detective. Face book boss account no exception. So the advise by @Rihana is sound for need to be strong about the issue. Thanks and Regards. God - trust your password is safe & sound.
