List of social providers that will be available to perform the authentication. Most of the time you will specify a provider with the connection name, e.g. 'facebook'. When the connection's 'name' and 'strategy' don't match, you'll need to provide an object with those properties, e.g. '{name: "my-connection", strategy: "facebook"}'. This option doesn't have a default value and must be specified when opening the Lock with a method that provides social authentication.
