The ultimate silver bullet to protect your account, computer and data is using a sufficiently complex and unique password combined with a second-factor token, i.e. in addition to the password you know, something you have, like your smartphone or a hardware token. This authentication process is known as two-factor authentication. It presents a huge hurdle for any attacker, as they would need to not only acquire your password, which can be achieved virtually ("CERN has been phished again"), but also physically steal your hardware token. And you would know if your smartphone got lost, wouldn't you?
