    Benefits Reduces phishing issues Reducing password issues due to different user name and password combinations Reducing time spent re-entering passwords for the same identity Can support conventional authentication such as Windows  / Linux and Mac credentials Reducing IT costs due to lower number of IT help desk calls about passwords Security on all levels of entry/exit/access to systems without the inconvenience of re-prompting users Centralized reporting for compliance adherence.
