I agree all of us need to be extra careful regarding in handling our wallet.We should make a back-up in order to secure our account and make sure all your private keys are backed-up.
If you have millions in your wallet or account and someone knows your password or you are logging in to your account in front of someone and he copied that then you are in trouble because he can access into your account and can simply cash out your millions. Now you have to take care of your privacy so that you will be safe and this is your security which is in your own hands.
