Hi, I am fascinated by the fact that you can use a single account to access the Google Suite. Can you describe more about the Google Apps single sign on in brief?
Description About Google Apps Single Sign On In Brief.
Single Sign-ON (SSO) helps the user to access all of their applications on cloud including the admin signing in through Admin console. They provide SAML-based SSO API which integrates with your Light weight Directory Access Protocol (LDAP). Chrome devices support SSO along with the Android devices. You can access every app from Google like Gmail, G+, Youtube, etc. using a single account.
