A strong password is two things: easy to remember, and hard for computer programs to "hack."

Suggestions:

• Use the first letters of a title or song. Then change some letters into numbers, and add special characters and spaces.
  Example: She loves you, yeah! yeah! yeah! Sluyyy = sluY!x3
  
• Create a phrase using odd spelling (substituting z for s, for example). Maybe leave out all the vowels.
  Examples:
  Success is mine = 6ZessZiZmine
  My goal is to retire at 55= G0Ls2rtr@55
  Take a hike = T&ke@H1ke
  White Sox win the Series in 2015 = 20Sox15winit

• Don't use words spelled the way they are in the dictionary
  
• Don't use keyboard sequences like asdfgh
  
• Don't use dates, addresses, or other information people can find out about you easily. Use a date only you know is important - like your first date with your spouse.
