Verify your users.
Security starts with accurate user identification. Tableau supports industry-standard authentication, including Active Directory®, Kerberos, OpenID Connect, SAML, trusted tickets and certificates. Tableau solutions also have their own built-in user identity service: Local Authentication.
Anyone in your organization must be represented as a user in the Tableau identity store. Tableau creates and maintains an account for each named user, which persists across all sessions for consistency.
