It's tough to remember a series of strong passwords and use a different one for each online system or site you access. The temptation is to use the same password for several or all systems and sites. That's a bad idea -- if a Bad Guy gets a hold of your password, he'll have the key that fits all of your doors. Instead, create a strong "core" password and then unique variations on it for each online system or site system you use. Here's a strong password: 5P0ky!3Z. It contains 8 characters, a mixture of uppercase and lowercase letters, at least one number and one non-alphanumeric character or symbol, and no personally identifiable information. By adding a character or two at the beginning or the end, you can have many variations to use for each system or site -- effectively creating a new strong password for each one. Remember to change your "core" password and its variations on a regular basis.
