For organizations seeking to extend their Identity platform to enable digital business models that engage customers and partners the key building block is Entra External ID.
Entra External ID represents an evolutionary step in unifying secure and engaging experiences across all external identities including customers, partners, citizens, and others within a single, integrated platform.
It includes all familiar features of Azure AD External Identities plus new capabilities, now in public preview, including developer-centric tools to build secure, compliant web and mobile applications for your customers, citizens, and partners – within minutes.
External Identities in Microsoft Entra supports CIAM and B2B applications so you can leverage beloved B2C features like customization, security, and extensibility in a familiar but new platform.
Azure AD B2c
For customers Azure Active Directory (Azure AD) B2C is a high-scale and powerful platform to configure sign-up, sign-in, and profile management for customer-facing applications. Azure AD B2C is generally available today.
As the documentation explains Azure AD B2c Azure provides business-to-customer identity as a service. Your customers use their preferred social, enterprise, or local account identities to get single sign-on access to your applications and APIs.
Azure AD B2C is a customer identity access management (CIAM) solution capable of supporting millions of users and billions of authentications per day. It takes care of the scaling and safety of the authentication platform, monitoring, and automatically handling threats like denial-of-service, password spray, or brute force attacks.
For developers looking to build applications that utilize these foundations Microsoft offers a range of best practice resources and case study examples.
This video walks through creating secure identities for apps using the Microsoft identity platform, and this session is intended for identity architects and developers who want to leverage Azure AD B2C as their authentication solution for their custom developed applications.
The overall best practices are defined as ‘CIAM’ – Customer Identity Access Management, principles explained in this webinar where Yoel Horvitz and Namita Singh explain how External Identities in Microsoft Entra supports CIAM and B2B applications so you can leverage B2C features like customization, security, and extensibility in a familiar but new platform.
The Tech Accelerator provides this in-depth tutorial on how to build secure and scalable apps with Entra External IDs, and in this case study Nitro explains how they are utilizing Microsoft Azure to enable their digital signing and identity solution world-wide. They also talk about how they tackle data residency challenges when working across countries.
