title: Does devise_token_auth use JSON web tokens?
body: <p>I am creating a new SPA with a REST API and for the backend I am using Rails with devise_token_auth. I am new to token authentication and while searching I am seeing a lot of libraries for frontend libraries that support JWT but I can't tell if this is compatible with devise_token_auth. </p>
  
  <p>Is JWT the standard for web tokens and is it what devise_token_auth uses?</p>
