Which of the following practices is likely to be prohibited by a user account policy?

Sharing passwords among coworkers is likely to be prohibited by a user account policy because it poses significant security risks. Password sharing increases the chances of unauthorized access to sensitive systems or data, as it undermines the principle of individual accountability. Each user is responsible for their own account and its security, and sharing passwords can lead to confusion over who accessed what information and when. In contrast, using multifactor authentication, updating passwords regularly, and reporting suspicious activities are practices that enhance security and are generally encouraged in a user account policy. These practices help in safeguarding user accounts against unauthorized access and in maintaining the overall security posture of the organization.
