Question

Quizplus · Accepted Answer

The unique key known only by the system and the person with whom the key is associated is the password. A password is a secret combination of characters used to authenticate a user's identity when logging into a system. It is a form of authentication that provides confidentiality and ensures that only authorized users have access to sensitive information. Tokens, user names, and user IDs are not necessarily unique keys known only by the system and the person with whom they are associated.
