I will implement azure ad b2c custom policies and oauth authentication

User Flows are point-and-click and cover basic scenarios. Custom Policies (IEF) are XML-based and required for anything advanced — REST API calls during auth, complex MFA, custom HTML branding, claims transformation, or multi-provider federation. Most production apps eventually need Custom Policies.

Not necessarily. The Basic package includes B2C tenant creation. You do need an Azure subscription (or I can help you set one up). B2C has a free tier — 50,000 monthly active users are free, so most startups pay nothing for the auth infrastructure itself.

Azure AD B2C, now part of Microsoft Entra External ID, is a cloud-native Customer Identity and Access Management (CIAM) solution. It allows organizations to authenticate and manage external users with custom identity policies (IEF), OAuth2/OpenID Connect/SAML federation, adaptive MFA, conditional ac

The Identity Experience Framework (IEF/IEF2) is the policy engine that enables fully customizable authentication journeys using XML-based Trust Framework files. It provides granular control over claims providers, claims transformation, orchestration steps, REST API integrations, social/enterprise Id

Yes. Azure AD B2C supports OAuth2, OpenID Connect (OIDC), and SAML 2.0 identity provider federation. This includes Google, Facebook, Apple, Microsoft, Azure AD, and custom enterprise IdPs. It enables single sign-on (SSO), token exchange, custom claims mapping, and seamless external identity handshak

Yes. Azure AD B2C enables custom multi-factor authentication (MFA) orchestration using risk-based triggers, progressive MFA escalation, custom OTP delivery, conditional access logic, API-verified MFA, and step-up authentication. This ensures fraud-resistant CIAM, identity assurance, and dynamic secu

Yes. Organizations can deploy fully branded login pages on custom domains with dynamic query string support, responsive UI, multi-language localization, conditional UX, and identity branding for mobile and web apps. This is essential for businesses building white-label CIAM, custom authentication UX

The Premium package includes integration with your existing app using MSAL (Microsoft Authentication Library). I'll provide working code samples and configure the redirect URIs, scopes, and token validation. Full app development is outside scope but I can guide your developers through integration.

Yes, this is covered in the Premium package. B2C supports seamless user migration (lazy migration on first login) and bulk migration via the Graph API. I'll design the migration strategy based on your user volume and password hash format.
