Compatible protocols

The Basic Authentication plugin is compatible with the following protocols:

grpc, grpcs, http, https, ws, wss

Parameters

Here's a list of all the parameters which can be used in this plugin's configuration:

• name or plugin

  string required

  The name of the plugin, in this case basic-auth.

  • If using the Kong Admin API, Konnect API, declarative configuration, or decK files, the field is name.
  • If using the KongPlugin object in Kubernetes, the field is plugin.

• instance_name

  string

  An optional custom name to identify an instance of the plugin, for example basic-auth_my-service.

  The instance name shows up in Kong Manager and in Konnect, so it's useful when running the same plugin in multiple contexts, for example, on multiple services. You can also use it to access a specific plugin instance via the Kong Admin API.

  An instance name must be unique within the following context:

  • Within a workspace for Kong Gateway Enterprise
  • Within a control plane or control plane group for Konnect
  • Globally for Kong Gateway (OSS)

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

• enabled

  boolean default: true

  Whether this plugin will be applied.

• config

  record required
  • anonymous

    string

    An optional string (Consumer UUID or username) value to use as an “anonymous” consumer if authentication fails. If empty (default null), the request will fail with an authentication failure 4xx. Please note that this value must refer to the Consumer id or username attribute, and not its custom_id.

  • hide_credentials

    boolean required default: false

    An optional boolean value telling the plugin to show or hide the credential from the upstream service. If true, the plugin will strip the credential from the request (i.e. the Authorization header) before proxying it.

  • realm

    string required default: service

    When authentication fails the plugin sends WWW-Authenticate header with realm attribute value.
