How does the use of a "single sign-on" access control policy improve the security for...

 Single sign-on (SSO) is an access control policy that allows users to authenticate with multiple applications and services by logging in only once. This approach improves security by reducing the number of credentials users must manage, which in turn decreases the likelihood of users writing down passwords. When users have to remember multiple complex passwords, they are more likely to write them down, use simple passwords, or repeat the same password across different services, all of which are security risks. SSO simplifies the login process, which can lead to stronger, unique passwords and reduce the risk of password-related breaches.
