Try the following code. You should be able to authenticate. There are a few extra things you need to set up. Follow this document for more details.

resource :sign_in do
  desc "Authenticate user"
  params do
    requires :login, type: String
    requires :password, type: String
  end
  post :login do

    user = User.find_by_email(params[:login].downcase)
    if user && user.authenticate(params[:password])
      token = TokenGenerator.create(user_id: user.id)
      {token: token.access_token}
    else
      error!('Unauthorized.', 401)
    end

  end
end
