Modern 42, a specialist identity advisory and engineering consultancy, today announced a collaboration with Microsoft to support organisations migrating from Azure AD B2C to Microsoft Entra External ID in Australia.
By combining Microsoft's modern identity infrastructure with Modern 42's deep engineering expertise in customer identity and Australian regulatory compliance, Australian organisations across healthcare, financial services, government and retail can confidently migrate their B2C solutions to Entra External ID.
What is Microsoft Entra External ID?
Microsoft Entra External ID represents Microsoft's next-generation customer identity platform, designed to securely manage external identities at enterprise scale. Built natively within the Microsoft Entra suite, External ID provides advanced security, governance, and developer capabilities to power modern digital experience across applications, APIs and ecosystems.
With Azure AD B2C no longer available for purchase by new customers as of May 2025, organisations are now looking to migrate to Microsoft's strategic CIAM platform Entra External ID. This migration will ensure their CIAM channels are operating on technology which is modern, supported and is being continuously improved. External ID not only leverages the security and extensibility of Entra, it provides modern registration, sign-in and self-service reset flows out of the box. This provides what every CIAM solution should – a frictionless experience for customers with security built in.
Migrating existing B2C environments can involve significant complexity, including custom policies, user directories, application integrations, and downstream identity dependencies. Successfully transitioning these environments requires careful planning, architecture design, and phased implementation to minimise disruption to your customer facing services.

Through this collaboration, Modern 42 supports Australian organisations across the full Azure AD B2C to Entra External ID migration lifecycle, including:
- Migration Readiness Assessments.
