Introduction
In a federated environment, user authentication is separated from user access with the use of one or more external entities that provide independent authentication of user credentials. The authentication is then passed to one or more services, enabling users to access the services through SSO (Single Sign-on).
Okta is one of the providers generally used for cloud-based SSO.
Tableau Online is the analytics platform that is fully hosted on the cloud, which allows your organization to build, share, and collaborate around data discoveries. By implementing Okta integration with Tableau Online, the user can ensure appropriate and secured access via user provisioning and SAML single sign-on, to keep their teams moving at the speed of insight.
