They can then access Verifone Central without a separate password. ### Before you begin Your identity provider must support **SAML** or **OpenID Connect (OIDC)**. Okta and Azure Active Directory support these standards. SSO requires collaboration between your system administrators and Verifone IT. Contact your [Verifone representative](/verifone-central-getting-started/verifone-central/help-and-support.md) to begin the integration. ### How federated access works Verifone marks your organization as a **federated entity**. Every user in that organization becomes a **federated user**. Federated users must sign in through the organization's SSO flow. They cannot sign in with a Verifone Central password. ### What changes for federated users * **Change password** and **Reset password** are unavailable. * Password emails, including welcome and expiry emails, are not sent. * The standard sign-in flow directs users to their organization's sign-in system. * API key creation and use remain available. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.verifone.com/verifone-central-getting-started/verifone-central/account-management/single-sign-on-sso-authentication.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
