# Secure API Access with OIDC
|
|
|
|
!!! info "Traefik Hub Feature"
|
|
This middleware is available exclusively in [Traefik Hub](https://traefik.io/traefik-hub/). Learn more about [Traefik Hub's advanced features](https://doc.traefik.io/traefik-hub/api-gateway/intro).
|

|
|
OpenID Connect Authentication is built on top of the OAuth2 Authorization Code Flow (defined in [OAuth 2.0 RFC 6749, section 4.1](https://tools.ietf.org/html/rfc6749#section-4.1)).
|
|
It allows an application to be secured by delegating authentication to an external provider (Keycloak, Okta etc.)
|
|
and obtaining the end user's session claims and scopes for authorization purposes.
|
|
|
|
To authenticate the user, the middleware redirects through the authentication provider.
|
|
Once the authentication is complete, users are redirected back to the middleware before being authorized to access the upstream application, as described in the diagram below:

!!! note "Advanced Configuration"
|
|
|
|
Advanced options are described in the [reference page](../reference/routing-configuration/http/middlewares/oidc.md).
|
|
|
|
For example, you can find how to customize the session storage:
|
|
- Using a cookie ([Options `session`](../reference/routing-configuration/http/middlewares/oidc.md#configuration-options) (default behavior))
|
|
- Using a [Redis store](../reference/routing-configuration/http/middlewares/oidc.md#sessionstore).
