Federated Authentication Service

Last published : Oct 15, 2026
Citrix Federated Authentication Service (FAS) enables single sign-on (SSO) to Citrix virtual desktops and applications in environments where users authenticate through modern identity providers such as SAML or OpenID Connect (OIDC) that don’t supply a Windows password, ensuring seamless access to session hosts joined to an Active Directory domain.
For more information about securing your deployment with the Federated Authentication Service, see the Federated Authentication Service documentation in its own document.
