Microsoft Entra External ID

Microsoft Entra External ID adds CIAM features such as self-service registration to an organization's apps. Conditional access policies and multifactor authentication apply to customer sign-ins. On the Basic tier the first 50,000 monthly active users cost nothing, and Komatsu is quoted as putting all its external-facing applications on the service.
