If your staff uses a wide variety of different forms of software in their day to day work that requires the use of a username/password combination in order for them to access them, it can tie up a lot of time if they have to log into each one separately. Instead of this if you install single sign on authentication software you can save both time and frustration.
Single Sign On Simplifies Authentication
Once you start using single sign on authentication each employee can be issued an RSA token that can be plugged into a USB port so that they can easily access all software and databases that they have authorization to use. After the token is removed, security is restored and will keep those without the proper authentication from being able to enter these areas or use the software.
