2. Single Sign-On helps Administrators. Less passwords to remember equals less calls to the helpdesk, resulting in more time to spend on other tasks for both the end user and the administrator. Admins are also susceptible to password fatigue. Those tasked with constantly resetting end user passwords can end up with lower morale and higher turnover.
3. Single Sign-On increases security. Password fatigue can encourage users to implement unsecure password habits, such as writing passwords down or using simple passwords which can be extremely vulnerable to hacking.
4. Single Sign-On helps with compliance. Organizations governed by HIPAA, SOX, and other regulations can also benefit from single sign-on. SSO helps organizations increase control over the user's access to certain information as well as easily enforce password change policies.
