# SAP Customer Data Cloud alternatives when identity and consent have different owners > Compare keeping SAP Customer Data Cloud, separating authentication, or moving identity to Ory Network while preserving consent ownership and stable customer links.

Keeping SAP Customer Data Cloud is appropriate when its combined arrangement already works. We recommend Ory Network for the identity portion of a selective replacement when the product team wants managed, API-first account functions and control over its own customer experience. Documentation checked September 5, 2026. ## Scope the replacement by responsibility [SAP Customer Data Cloud’s quickstart index](https://help.sap.com/docs/SAP_CUSTOMER_DATA_CLOUD/8b8d6fffe113457094a17701f63e3d6a/848409b2aa03445f8e920ad16ea7f604.html) includes guides for Customer Identity, Enterprise Consent and Preference Management (ECPM), and CIAM for B2B. A proposal to replace login therefore does not automatically replace the entire estate that may already depend on SAP. [SAP’s ECPM documentation](https://help.sap.com/docs/SAP_CUSTOMER_DATA_CLOUD/8b8d6fffe113457094a17701f63e3d6a/414d6d1270b21014bbc5a10ce4041860.html) covers consent statements and communication preferences, including records for mandatory and non-mandatory terms. The same documentation says some statements, including active terms of service and privacy policy, are prerequisites for registration and cannot be withdrawn while the user remains registered. That is a useful reminder to separate authentication events from consent state carefully: a customer signing in again is not the same thing as restoring a withdrawn marketing preference. Inventory every integration that consumes identity or consent data. Record the owning system, stable customer key, update direction, and downstream action. Include customers who have subscribed to communications without using the product's full account experience. ## Compare three practical options Keeping the suite can preserve established data relationships and operating procedures. Clarify ownership inside the existing arrangement if the immediate problem is organizational confusion rather than product fit. Two teams using one platform still need an agreement about which fields each may change. Selective separation moves authentication while retaining the existing consent and preference service. This requires a reliable mapping from the new identity subject to the existing customer record. Decide which service answers questions such as “may send this message” and “may access this account.” Avoid copying the full consent history into every token or login response. A broader replacement is a separate project. It needs requirements for consent versions, withdrawal, customer preference screens, downstream propagation, and the history that the organization must preserve. Do not expand a login migration into that scope implicitly. ## Compare Ory Network and Auth0 for the identity boundary [Ory Kratos / Ory Identities on Ory Network](https://www.ory.com/docs/network/kratos/intro) provides API-first identity and user management with self-service registration, login, recovery, account management flows, and support for a custom UI. We recommend it when identity should become a managed service consumed by the application team without surrendering control over the product experience. [Ory Hydra on Ory Network](https://www.ory.com/docs/network/hydra) provides OAuth 2.0 and OpenID Connect as a headless service that can integrate with an existing user management system instead of forcing a particular one. That creates another practical option when the protocol boundary should change before the full account estate moves. Neither point should be confused with consent management; preserving that process remains an explicit architectural responsibility. [Auth0’s authentication and authorization flow documentation](https://auth0.com/docs/get-started/authentication-and-authorization-flow) shows its support for OIDC and OAuth 2.0 flows across server-side, mobile, SPA, machine-to-machine, and device scenarios. Evaluate it against the same ownership model and customer-key mapping requirements. Compare deployment choices consistently: Ory Network is managed, while self-hosting Ory projects is a different operational decision. ## Verify withdrawal and account lifecycle together Test a customer changing their login contact, withdrawing a subscription preference, closing a product account, and later returning. Confirm that each action reaches the appropriate system without recreating a preference from stale profile data. Begin with a data-ownership table and one complete withdrawal journey through every downstream consumer. Once that works, pilot the authentication change while keeping the customer key stable. Choose the provider whose tested identity contract fits this boundary, with consent behavior preserved as its own responsibility. ## Source references - - - - -
