Microsoft announced the addition of an Azure Active Directory (AD) sign-in history feature that would allow users to get an overview of past sign-ins and quickly detect any unusual login activity. Azure AD users will be able to discover potential password-based attacks easier and take action to limit any harmful effects a potential account compromise might have. Microsoft also announced this month that 16 new Azure AD lower-privileged roles are now available in preview to help admins boost security by decreasing the total number of Global administrators.
