An external authentication service that manages and verifies user identities for LogScale. Identity providers handle user authentication, credential management, and often provide additional services like single sign-on (SSO), multi-factor authentication (MFA), and group membership information. LogScale supports various identity providers including Azure AD/Entra ID, Okta, Google Workspace, Active Directory Federation Services, PingFederate, and Duo Security through protocols like SAML 2.0, OpenID Connect (OIDC), and OAuth 2.0. When configured, LogScale redirects users to the identity provider for authentication and receives tokens or assertions to validate user access, enabling centralized user management and enhanced security.
