Passwords

Make passwords difficult to guess
Add punctuation or numbers as in hot*pizza or thi5i5mine.

Change your passwords often
That doesn't mean once a year whether you've been attacked or not; it means changing passwords as often as every two weeks, or every month at a minimum. It's not as convenient, but convenience and security don't always go together.

Combine the first letters of a common phrase or saying to create a password For example, you might take the phrase "If elected I promise to lower taxes for all" and turn it into the password "ieip2ltfa".

Avoid obvious word, real names, or dates....
... that mean something in your life, because a hacker who knows you may guess them.
