Abstract : The use of a password as the only traditional user authentication mechanism has been criticized for its weakness in computer security. One problem is for the user to select short, easy to remember passwords. Another problem is the selection of a password that is too long which the user tends to forget. Long passwords tend to be written down carelessly somewhere in the work space. Such practices can create serious security loopholes. Consequently, this is a survey of alternative password mechanisms and other improved devices that are now available in the marketplace to enhance computer security. It taxonomizes the existing inventory of user authentication mechanisms such as biometrics, challenge/response, password, smart card and token.
