Keep changing your password often

Facebook has an application that shows how strong the password you are using, really is. Make sure you always choose a password that nobody else will guess. Avoid using obvious things like your date of birth, name, boyfriends name and so on. Instead you can mix numbers and alphabets to make a really strong password for your Facebook account. Your password is like the keys of your home, dont share it with anyone. Keep it only to yourself and change it often.
