Now you have the responsibilities outlined in the previous paragraph. The key to this whole process is clear communication of goals and responsibilities. The single most important component of computer security is your password. Computers protect information by making sure only authorized people can access it. We recognize people by a variety of visual, audio, and behavioral clues.
Computers primarily recognize people by their user ID and password.
The password is the system's only way to authenticate your identity. So you have to convince the system you are you through the magical password. The computer science majors will tell you the best password is a 40 character string of random letters and numbers. The psychology majors might argue a short English word or name closely related to you is better because it is easier to remember. Because the comp sci majors run the computers, many systems assign random passwords.
