One of the biggest problems today on internet and through internet is the problem of hacking. the person whose computer or any other device gets hacked looses on his personal information to others and the hacker may even misuse the information. a person should keep in his mind that passwords are to be handled by cautions and it is not a thing that should be shared or else it can get you into trouble. ideally a user of any social media or any website should change his password in every three to four moths to avoid any problem.
