Source stage

Enterprise

The Source stage sends the user to an OAuth or SAML source before returning to the flow.

About the source stage​

Use this stage when an external identity provider should be part of the current authentik flow, for example during staged migrations or additional external verification.

Common examples include:

  • Authenticating against a legacy IdP such as Microsoft Entra ID, Google Workspace, or Okta during an IdP migration and then using the returned identity and attributes inside authentik
  • Routing users through an external OAuth or SAML identity provider
  • Sending users through a custom device-health or posture-check system before continuing

For pure authentication or enrollment, an OAuth or SAML source can also be used directly without a Source stage. Use the Source stage when that external step needs to be embedded inside another authentik flow.

Configuration options​

  • Source: the OAuth or SAML source to use.
  • Resume timeout: how long authentik keeps the suspended flow available while the user is away at the external source.

Flow integration​

Bind this stage to a flow when the user should authenticate or enroll through an external source and then return to the authentik flow.

The configured source must be a browser-based source such as OAuth or SAML. LDAP and other non-browser sources are not compatible.

Notes​

Important source-flow behavior​

Do not bind a User Login stage to the source's own authentication or enrollment flow.

The Source stage resumes the original flow by appending a dynamic in-memory stage to the source flow. If the source flow logs the user in directly, the original flow will not resume correctly.

Workflow​

Resume timeout​

If the user takes longer than the configured timeout to return from the external source, the original suspended flow is discarded and the flow restarts from the beginning on return.
