BasicAuth

Adding Basic Authentication {: .subtitle }

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.

!!! Note

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

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

apiVersion: traefik.containo.us/v1alpha1

spec:
  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.)
