Password protection is everywhere nowadays. To get the most out of your passwords, remember the following:

• Never use the same password twice. If the security of one of your accounts is compromised, then all of your accounts that use that same password are endangered as well.
  
• Always write your passwords down, even if you think you can remember them. Keeping a couple dozen passwords straight in your memory can be pretty hard, especially if some of them are for sites that you don't visit regularly.
  
• Never leave your passwords lying around. No matter how careful you are in picking passwords, they aren't secure if you don't protect them. You'd be amazed by the number of people who tape their passwords to their computer monitors!
  
• Change your password from time to time. If you have a password for a Web site that is very important to you, change the password more often than usual.
