Single Sign-On (SSO) allows the use of a single password to log in to any number of independent software and applications. This provides an additional advantage of creating a difficult and strong password that can be the only one to be remembered. It eliminates the need to manually log into each separate application and thereby offers big benefits to users and administrators
An example of a very common SSO authentication style is the Google suite of applications. The credential of a single Google account is enough to log in to all the available Google applications. Essentially, it improves compliance through a centralized database.
