Hi @Michal Durista , I'll try to answer your questions the best I can. If I leave anything out or you have more questions please let me know.
- Microsoft Entra ID is not a new name for Azure AD. Microsoft Entra is a new brand that encompasses a range of identity and access management (IAM) solutions, including Azure AD, Azure AD B2C, and Microsoft Identity Manager (MIM).
- Azure AD B2C is a separate service from Azure AD, but it is part of the Microsoft Entra family of IAM solutions. Azure AD B2C is designed specifically for customer-facing applications and provides features such as social identity providers, custom branding, and self-service password reset.
- Microsoft Entra External ID is a new CIAM solution that is built on top of Azure AD B2C. It provides additional features and capabilities, such as a simplified user interface, improved developer experience, and enhanced security. However, it is a separate service from Azure AD B2C and has its own pricing and licensing model.
Between Azure AD B2C and Microsoft Entra External ID, the main difference is in the user and developer experience. Microsoft Entra External ID provides a more streamlined and intuitive user interface, as well as improved developer tools and documentation. It also includes additional security features, such as risk-based authentication and adaptive access policies. However, the underlying functionality and capabilities are similar to Azure AD B2C.
About pricing, Microsoft Entra External ID is currently in preview, so pricing details are not yet available. The pricing information you found may be related to other Microsoft Entra solutions, such as Microsoft Entra Identity Protection or Microsoft Entra Privileged Access Management. I would reach out to sales for any questions related to pricing.
Please let me know if you have any questions and I can help you further.
