BasicAuth

The BasicAuth middleware is a quick way to restrict access to your services to known users.

Configuration Examples

# Declaring the user list
#
# Note: all dollar signs in the hash need to be doubled for escaping.
# To create user:password pair, it's possible to use this command:
# echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g

Configuration Options

General

Passwords must be encoded using MD5, SHA1, or BCrypt.

!!! tip

Use `htpasswd` to generate the passwords.

users

The users option is an array of authorized users. Each user will be declared using the name:encoded-password format.

usersFile

The usersFile option is the path to an external file that contains the authorized users for the middleware.

The file content is a list of name:encoded-password.

??? example "A file containing test/test and test2/test2"

```txt
test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/
test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0
```

!!! Note

If both `users` and `usersFile` are provided, the two are merged. The content of `usersFile` has precedence over `users`.

realm

You can customize the realm for the authentication with the realm option. The default value is traefik.

headerField

You can define a header field to store the authenticated user using the headerFieldoption.

labels:
  - "traefik.http.middlewares.my-auth.basicauth.headerField=X-WebAuth-User"
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: my-auth
spec:
  basicAuth:
    # ...
    headerField: X-WebAuth-User
"labels": {
  "traefik.http.middlewares.my-auth.basicauth.headerField": "X-WebAuth-User"
}
[http.middlewares.my-auth.basicAuth]
  # ...
  headerField = "X-WebAuth-User"
http:
  middlewares:
    my-auth:
      basicAuth:
        # ...
        headerField: "X-WebAuth-User"

removeHeader

Set the removeHeader option to true to remove the authorization header before forwarding the request to your service. (Default value is false.)
