Enable Single Sign-On
Microsoft Azure Active Directory (AD) single sign-on (SSO) enables users to sign in just one time to applications in the Microsoft Azure AD in order to access integrated applications.
With Azure AD SSO, users can sign in with one account to launch applications from the Office 365 portal, Dynamics 365, or the Azure AD MyApps access panel. Moreover, administrators can control user account management, and automatically add or remove user access to applications based on group membership. Without SSO, users have to remember passwords and sign in to each application separately.
For configuration steps, see Tutorials for Admins, section Microsoft Azure Active Directory SSO Configuration.
