The Single Sign-On (SSO) Advantage.
Users can enjoy a seamless experience by using a single username and password to access their day-to-day Google Workspace applications (Gmail, Drive, Meet, Calendar, etc.) as well as their coexisting Office 365 applications. Through this method, users can also access their Office account from the Application launcher, as shown in this image.
Administrators can find SAML applications by clicking on Apps > SAML Apps in the Google Workspace Admin Console. As soon as the SAML application has been set up, it can be turned on for everyone or for select sub-organizations. The gif below shows how Google Workspace Admins can configure this.
