You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: authentication.rb
    path of file: ./repos/forest-rails/app/services/forest_liana
    
    the code of the file until where you have to start completion: module ForestLiana
  class Authentication
    def start_authentication(state)
      client = ForestLiana::OidcClientManager.get_client()

      authorization_url = client.authorization_uri({
        scope: 'openid email profile',
        state: state.to_s,
 
    
    def verify_code_and_generate_token(params)
      client = ForestLiana::OidcClientManager.get_client()

      rendering_id = parse_state(params['state'])
      client.authorization_code = params['code']

      if Rails.env.development? || Rails.env.test?
        OpenIDConnect.http_config do |config|
          config.ssl_config.verify_mode = OpenSSL::SSL::VERIFY_NONE
        end
      end
