Microsoft Entra External ID Expert – Membership Application Authentication

We are looking for an experienced Microsoft Entra External ID (CIAM) expert to help us design and validate the authentication architecture for an existing membership application. Our application currently uses Microsoft Entra ID for user authentication. Existing members can successfully sign in; however, we now need to enable secure authentication for external users (non-members) who do not have accounts within our Microsoft Entra tenant. We are looking for someone who can: * Review our current authentication approach. * Design the most appropriate Microsoft-based solution for external user authentication. * Validate that the proposed architecture is complete, secure, scalable, and aligned with Microsoft best practices. * Identify any gaps, edge cases, security considerations, or implementation risks before development proceeds. * Provide a clear solution design and implementation recommendations. If you have hands-on experience designing and implementing Microsoft Entra External ID (CIAM) solutions, we'd love to hear from you. When applying, please include: * A brief summary of similar projects you've completed. * Your experience with Microsoft Entra External ID (CIAM). * Your availability for an initial discussion.
