Single sign on authentication is a method used by some organizations for users to gain access to different resources. This method involves only requiring users to enter their information a single time. After it is entered, their computer stores the data and uses it to authenticate with various resources and systems in the background, whenever they are opened or accessed.
One Advantage of Single Sign on Authentication Can Also Be a Drawback
One main advantage to using single sign on authentication is not requiring users to remember multiple user IDs and passwords. Instead, a single ID and password will work for all of the applications and resources which your users are allowed to access. However, this advantage can also be a drawback, because anyone who knows someone else’s user ID and password can use it to gain access to resources or applications which they may not be allowed to access using their own ID and password. You can safeguard against this situation by adding a second layer of security, which is available through a different method called two factor authentication.
