Changes

Tokens involve the use of what are essentially one time passwords to gain access to a system. These tokens can be generated using small devices such as smart cards or key ring devices which display a new token each time the user press a button, which is sued used to gain access to a system or server. Each token is unique and used only once, avoiding the problem of password falling into the wrong hands. Even if a token was to fall into the wrong hands it would be invalid before they had a chance to use it to gain unauthorized access.
