Aberdeen Research Brief - The Many Faces of Single Sign-on

Organizations are supporting far too many passwords, which leads to weakened security, inconvenienced end users, and increased cost of management and support. Several approaches are available to help companies work towards the ideal of a single sign-on, including directory synchronization, password synchronization, enterprise single sign-on, web access management, and identity federation. This Research Brief leverages the findings of recent Aberdeen research on user authentication to provide insights into the factors that should influence selection among these different approaches to a common problem.
