'Credentials' is the rather formal title of November's NoticeBored security awareness module, but in fact the materials cover a wider brief relating to identification and authentication.
Authentication associates a person unambiguously to an identity, excluding others. It reduces the possibility of fraud and hacking, helps maintain the integrity of the systems and data, and is a prerequisite for personal accountability. Authenticated individuals can safely be given access to sensitive and valuable information resources which they are authorized to access. Without authentication, unauthorized access would be a much bigger problem and the information security risks would be even greater.
That said, from the ordinary employee's perspective, the key issues are choosing good passwords and keeping his staff ID card safe.
