Customer identity and access management

Azure Active Directory B2C is a cloud identity service allowing you to connect to any customer who puts your brand first. Governments and enterprises worldwide are using Azure Active Directory B2C to serve their applications to their citizens and customers with fully customizable experiences, while protecting their identities at the same time. Built on Azure Active Directory, the highly-secure cloud identity platform that handles billions of authentications per day, Azure Active Directory B2C offers that same scale, reliability, and availability for your customer-facing applications.

Super simple or super custom

Flexibility is a key part of Azure Active Directory B2C. You can choose from two configuration options to suit your needs. Use built-in policies to create a login experience in minutes. For more complex scenarios, use our identity experience framework to build custom policies and integrate with CRM databases, marketing analytics tools, and account verification systems.

Reach any user on any platform

Build an identity experience that works everywhere on Android, iOS, or web. Make it easy for your customers to access your application by allowing them to sign in with their existing social accounts or personal emails. Azure Active Directory B2C supports Facebook, Microsoft Accounts, Google+, LinkedIn, and many others, or you can add your own.

Protect your customers’ identities

Your customers will rest assured that their profiles are protected through various security controls in addition to application or policy-based multi-factor authentication.

Supports open standards to integrate with all technology stacks

Connect to your user accounts using industry standard protocols such as OpenID Connect or SAML to make identity management possible on a variety of platforms, such as Microsoft .NET and Node.js. Through support for OAuth 2.0, developers can build their own secure web APIs, and open-source client libraries are available for .NET, Windows Store, iOS, and Android—and we’re constantly developing additional libraries.

Scale to hundreds of millions of customers

Let us help you scale to as many users as you need while providing you maximum availability. Azure Active Directory B2C is a reliable, globally-distributed service with an SLA of 99.9%, capable of supporting millions of users and billions of authentications per day.
