Configuration Options

!!! tip

Use `htdigest` to generate passwords.

users

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

!!! note ""

- If both `users` and `usersFile` are provided, the two are merged. The contents of `usersFile` have precedence over the values in `users`.
- For security reasons, the field `users` doesn't exist for Kubernetes IngressRoute, and one should use the `secret` field instead.

    ]

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:realm:encoded-password.

!!! note ""

- If both `users` and `usersFile` are provided, the two are merged. The contents of `usersFile` have precedence over the values in `users`.
- Because it does not make much sense to refer to a file path on Kubernetes, the `usersFile` field doesn't exist for Kubernetes IngressRoute, and one should use the `secret` field instead.

realm

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

headerField

You can customize the header field for the authenticated user using the headerFieldoption.

  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.)
