This is where Microsoft Entra ID B2C shines. Entra ID B2C is a cloud-based identity and access management solution designed specifically for customer-facing applications. Unlike traditional identity systems focused on employees, Entra ID B2C is tailored to handle the complexities of managing external identities at scale.
At its core, Entra ID B2C is built on a highly scalable architecture that supports millions of identities.

One of the standout features of Entra ID B2C is its customisation capabilities. Organisations can design branded user interfaces for login, registration, and password reset flows, ensuring a cohesive customer experience. Additionally, the service supports advanced identity management scenarios, such as multi-factor authentication (MFA), social identity integration (e.g., Google, Facebook, LinkedIn), and custom policies for complex workflows.
Entra ID B2C also provides robust data processing capabilities. It securely stores customer data in compliance with GDPR, CCPA, and other regulatory requirements. With built-in analytics, organisations can monitor user behaviour, authentication trends, and security metrics to optimise their identity management strategy.
