Azure Active Directory B2C

Chuck Waters

Senior Software Architect

Azure AD B2C is a customer identity access management (CIAM) solution that enables you to sign up and sign in your customers into your web and mobile applications. Azure B2C provides a custom-branded identity solution that supports social and enterprise accounts, as well as integration with external user stores and third-party systems.

Some of the advantages of implementing Azure B2C across different platforms are:

You can use the same authentication and authorization logic for all your web platforms, regardless of the programming language or framework you use. Azure B2C supports standards-based protocols such as OpenID Connect, OAuth 2.0, and SAML, which can be easily integrated with most modern applications and libraries.
You can customize the user experience and user interface of your identity solution to match your brand and application design. Azure B2C lets you customize the HTML, CSS, and JavaScript of your user flows, as well as the language and domain of your identity pages.
You can scale your identity solution to handle millions of users and billions of authentications per day, without worrying about the performance and security of your authentication platform. Azure B2C handles the scaling and safety of your identity solution, monitoring and automatically handling threats like denial-of-service, password spray, or brute force attacks.
You can leverage the features and benefits of the Azure cloud platform, such as global availability, reliability, compliance, and integration with other Azure services. Azure B2C also supports hybrid and multi-cloud scenarios, allowing you to connect your identity solution with your on-premises or other cloud resources.
