# ForwardAuth
Using an External Service to Check for Credentials
{: .subtitle }
![AuthForward](../assets/img/middleware/authforward.png)
The ForwardAuth middleware delegate the authentication to an external service.
If the service response code is 2XX, access is granted and the original request is performed.
Otherwise, the response from the authentication server is returned.
## Configuration Examples
??? example "File -- Forward authentication to authserver.com"
```toml
[http.middlewares]
[http.middlewares.test-auth.forwardauth]
address = "https://authserver.com/auth"
trustForwardHeader = true
authResponseHeaders = ["X-Auth-User", "X-Secret"]
[http.middlewares.test-auth.forwardauth.tls]
ca = "path/to/local.crt"
caOptional = true
cert = "path/to/foo.cert"
key = "path/to/foo.key"
```
??? example "Docker -- Forward authentication to authserver.com"
```yml
a-container:
image: a-container-image
labels:
- "traefik.http.middlewares.test-auth.ForwardAuth.Address=https://authserver.com/auth"
- "traefik.http.middlewares.test-auth.ForwardAuth.AuthResponseHeaders=X-Auth-User, X-Secret"
