Identity-Provider-Initiated Single Sign-On

Overview of Single Sign-on (SSO) initiated by Identity Providers (IdPs).

For Identity-Provider-Initiated Single Sign-On (SSO), a third-party Identity Provider (IdP) is the SSO provider. When a user logs in to an application:

1. The application redirects the user to an identity provider.
2. The third-party identity provider performs authentication and authorization.
3. Upon successful authentication, the user is returned to the application.

Auth0 provides IdP-initiated SSO Integrations for various services, like Dropbox, Slack, or Zoom. To see the full list, explore Auth0 Marketplace: SSO Integrations.

You can also build your own implementation with SAML or OIDC:
