In order to log onto a network, you need a User ID and a password.
Your User ID identifies you to the network, it enables the server to retrieve your files and it defines your access rights. Your User ID does not need to be kept a secret.
Your password is the second part of the log-on security. It identifies that you are the person to whom the User ID belongs. It must be kept a secret.
Your password should be kept secure at all times, never written down or given out to other people. If others know your password, they can access your personal area on the network and read, alter or delete your files.
Passwords should be carefully chosen. They should not be something which is easily associated with you and could be guessed e.g. your favourite football team or your dog's name. They should contain a mixture of letters, numbers and symbols. This makes it difficult for special password cracking software to identify your password.
You should change your password regularly e.g. every month and if you think someone has found it out, you should change it immediately.
