HAVE A STRONG PASSWORD!
Never share your password. You never know who will hack it.
Never give out your password, that is one thing you should aways keep to yourself. If you feel like you need to share your password with someone a good person to tell is one of your family members because they have no reason to hack your account. You also should always change you password every one to two months because if you did accidentally tell your friend your password they will never know what you changed it to.
