Use variations of a strong "core" password…

It’s tough to create and remember strong passwords for each online system or site you access. It’s a BAD idea though to use the same password for several or all systems and sites! A helpful option is to create a strong "core" password and then use unique variations of it for the systems 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 info. By adding a character or two at the beginning or the end, you can have many variations to use - effectively creating a series of new strong passwords to use. Remember to change your "core" password and its variations on a regular basis.   Source: SANS Institute
