Azure AD B2C Implementation & Entra External ID
Enterprise Azure AD B2C and Microsoft Entra External ID implementation — branded customer sign-up, social login, MFA, custom policies and migration, delivered by Schutz IT across Australia.
What is Azure AD B2C?
Azure AD B2C (Azure Active Directory B2C) is Microsoft's cloud-based customer identity and access management (CIAM) service. It authenticates and manages the external users of your applications — customers, partners, citizens and contractors — with username/password, social logins (Google, Facebook, Apple, LinkedIn), enterprise federation (SAML, OIDC) and multi-factor authentication, all on a dedicated B2C tenant that scales to hundreds of millions of users. Alongside Azure AD B2C, Microsoft now offers Microsoft Entra External ID as the next-generation Azure CIAM platform. Schutz IT implements both — and migrates customers between them — so you get sign-up, sign-in, MFA, Conditional Access and identity governance without building an identity stack yourself.
Azure AD B2C vs Microsoft Entra External ID
If you're evaluating Azure CIAM today, the choice is between the mature Azure AD B2C and the newer Entra External ID. Here's how they compare:
| Capability | Azure AD B2C | Entra External ID |
|---|---|---|
| Status | Generally available, maintenance mode | Generally available, actively invested |
| User journey customisation | Custom policies (XML, steep learning curve) | User flows + native extensions |
| Conditional Access | Limited (basic risk policies) | Full Conditional Access engine |
| Continuous access evaluation | Not supported | Supported |
| Tenant model | Separate B2C tenant | Integrated with workforce Entra tenant |
| Best fit | Existing B2C deployments, complex legacy flows | New builds, B2B + B2C, regulated workloads |
Why enterprises pick Azure CIAM
- Scale — proven at hundreds of millions of customer identities on Microsoft's global Azure footprint.
- Security — MFA, passkeys, risk-based and conditional access, plus continuous access evaluation in Entra External ID.
- Compliance — data residency options across Australia, EU and US; aligned with ISO 27001, SOC 2, GDPR and the Australian Privacy Act.
- Standards — OAuth 2.0, OpenID Connect, SAML 2.0 and SCIM out of the box, so any modern app integrates cleanly.
- Ecosystem — native Microsoft 365, Dynamics, Power Platform and Azure integration cuts the integration cost of every downstream workload.
Pairing Azure CIAM with a properly governed Public Key Infrastructure (PKI) gives you end-to-end identity assurance — from the customer login flow down to the certificates that secure your APIs and devices. For deeper context, see our briefing on CIAM vs IAM.

Frequently Asked Questions: Azure AD B2C
What is Azure AD B2C?
Azure AD B2C (Azure Active Directory B2C) is Microsoft's cloud-based customer identity and access management (CIAM) service. It authenticates customers, partners and citizens with username/password, social logins (Google, Facebook, Apple, LinkedIn), enterprise federation (SAML, OIDC) and multi-factor authentication, all on a dedicated B2C tenant that scales to hundreds of millions of users. Azure AD B2C is generally available and remains fully supported by Microsoft.
How much does Azure AD B2C cost?
Azure AD B2C is priced per monthly active user (MAU). The first 50,000 MAUs are free in Premium P1, after which you pay a per-MAU price plus a small per-authentication charge for MFA via SMS or voice. Pricing depends on region and edition (P1 vs P2 for advanced risk and identity protection). Schutz IT can model your projected Azure AD B2C bill against your active customer base.
What are Azure AD B2C custom policies?
Azure AD B2C custom policies (Identity Experience Framework, or IEF) are XML-based definitions for advanced sign-up, sign-in and profile-edit journeys beyond the built-in user flows. They support REST API calls to your own systems, claims transformation, age gating, progressive profiling and complex federation. Custom policies are powerful but have a steep learning curve — Schutz IT designs and maintains them for clients who need flows that user flows alone cannot deliver.
Azure AD B2C vs Microsoft Entra External ID — which should I choose?
Microsoft Entra External ID is the next-generation evolution of Azure AD B2C. B2C uses a separate tenant and XML custom policies; Entra External ID lives inside your workforce Entra tenant, replaces XML with extensible user flows, and adds the full Conditional Access engine plus continuous access evaluation. New CIAM builds should usually default to Entra External ID. Existing Azure AD B2C tenants remain fully supported — there is no forced migration deadline.
How do I migrate from Azure AD B2C to Entra External ID?
An Azure AD B2C to Entra External ID migration runs in four phases: (1) inventory existing user flows, custom policies, identity providers and connected applications; (2) rebuild user journeys as Entra External ID user flows or extensions; (3) bulk-migrate user accounts (with credential re-hashing or just-in-time migration via REST APIs); (4) cut applications over one at a time using parallel issuers. Schutz IT delivers this so you keep both tenants live during the transition with no customer downtime.
Azure AD B2C vs Okta Customer Identity or Auth0 — which is better?
Azure AD B2C is usually the lowest-friction CIAM choice for organisations already standardised on Microsoft 365, Azure, Dynamics or the Power Platform — identities, billing and governance live in the same tenancy and per-MAU pricing is competitive at scale. Okta Customer Identity and Auth0 are strong alternatives when your stack is multi-cloud or when you need specific developer-experience features. Choose based on existing platform investments, regulatory requirements and the integrations on your roadmap.
How can Schutz IT help implement Azure AD B2C?
Schutz IT provides end-to-end Azure AD B2C implementation services — requirements analysis, B2C tenant setup, identity provider federation (Google, Facebook, Apple, LinkedIn, SAML enterprise IdPs), branded user flows, custom policies (IEF/XML), MFA and Conditional Access policy design, API and application integration, migration from legacy CIAM platforms, security hardening, testing, deployment, and ongoing managed support across Australia.
