Main plug that stores KeenAuth configuration in the connection.

This plug must be included in your pipeline before any KeenAuth functionality can be used. It stores the configuration in the connection's private data, making it accessible to controllers and other plugs.

Usage

Add the plug to your router pipeline:

pipeline :authentication do
  plug KeenAuth.Plug, otp_app: :my_app
end

scope "/auth" do
  pipe_through [:browser, :authentication]
  KeenAuth.authentication_routes()
end

Configuration

The plug accepts any configuration options that will be merged with your application's :keen_auth configuration. Common options:

• :otp_app - The OTP application name where configuration is stored
• :strategies - List of authentication strategies (usually in app config)
• :storage - Custom storage module (defaults to session storage)
