Why You Should Start Migrating from Azure AD B2C Now
On May 1, 2025, Microsoft will stop offering Azure Active Directory B2C (Azure AD B2C) to new customers. Existing B2C tenants remain supported until at least 2030—but all new feature investments and innovations will focus on Microsoft Entra External ID.
Key risks of delay
- Missing out on modern security features (conditional access, Identity Protection)
- Facing future integration hurdles with partner and customer workloads
- Scrambling under time pressure instead of following a strategic roadmap
Introducing Microsoft Entra External ID
Microsoft Entra External ID is a unified, cloud-native Customer Identity and Access Management (CIAM) solution that lets you:
- Scale to millions of external users with high availability
- Secure logins with built-in MFA, conditional access, and threat protection
- Customize user journeys with branded sign-up/sign-in pages and custom attributes
- Integrate any identity provider (social, enterprise, email-OTP, OIDC, SAML)
Migrating from Azure AD B2C to Microsoft Entra External ID unifies customer and partner scenarios under one platform and unlocks richer security and user-experience capabilities.
Key Steps for a Successful Azure AD B2C to Entra External ID Migration
There’s currently no direct “one-click” migration tool, but by following these structured steps, you can ensure a smooth and efficient transition:
1. Audit Your Azure AD B2C Tenant
- Catalog existing user flows (sign-up, sign-in, profile edit, password reset)
- Identify custom policies, API connectors, external identity providers, and key user attributes
- Map out integrations with your applications and services
2. Design Your New Entra External ID Tenant
- Rebuild user journeys with Entra External ID’s capabilities
- Set up branding, user attributes, and conditional access policies
- Integrate social identity providers and enterprise directories
3. Migrate Your User Base
- Export user accounts securely from Azure AD B2C
- Prepare user data for compatibility with Entra External ID (preserve emails, usernames, MFA enrollments)
- Plan for either seamless credential migration or implement secure password reset flows
4. Integrate Your Applications with Entra External ID
Traditionally, migrating to Entra External ID would require modifying your applications to point to new authentication endpoints—often involving significant code changes and months of engineering work. Or you can consider a no-code alternative like Datawiza Access Proxy.

How Datawiza Simplifies Your Migration from Azure AD B2C to Entra External ID
Datawiza Access Proxy lets you integrate Microsoft Entra External ID in front of your apps—without heavy rewrites. Here’s the flow:
- Proxy Deployment Deploy Datawiza Access Proxy as an identity-aware reverse-proxy in your network or cloud environment.
- Authentication Bridge When a user attempts to access your application, the proxy redirects them to Microsoft Entra External ID for sign-in and multi-factor authentication (MFA).
- Identity Injection After successful authentication, Datawiza Access Proxy retrieves the user’s claims (email, username, group memberships, custom attributes) and injects them into each request—either as HTTP headers or as a signed JWT token.
- Application Consumption Your application consumes these headers or JWT claims as its source of truth, enforcing authorization based on the injected identity data—no SDKs or embedded libraries required.
Benefits of Using Datawiza Access Proxy:
- Speed Up Your Migration Project: Quickly enable Entra External ID integration with minimal coding efforts.
- Free Up Your Developers: No need for months of SDK integration or authentication logic rewrites.
- Offload Long-Term Maintenance: Datawiza handles updates, security patches, and ongoing Entra External ID changes.
This no-code approach saves time, reduces risk, and simplifies ongoing identity management for your applications.
