With the Hearbleed Bug giving us all a timely reminder about the need to have secure passwords I think this article will help.
It examines six different password managers and recommends which you could use.
Password Managers basically store all your passwords in an encrypted state so no one can hack them. You still need 1 master password to be able to access, create and store new passwords. They usually help you create secure passwords as well which you then copy and paste into the password box of whatever program or website that is asking for one.
This is much better than the way most people use which is the kids/dogs/cats name! Hackers just love those ones...
