title: Proper way for user authentication with angularjs and flask
body: <p>I'm currently working my way through Web development with flask. I want to build a webapp with flask as backend and angular.js at the frontend. The Json part is straight forward, and my first steps work out well. But now I got stuck with User Authentication. I read a lot but found out, that WTFForms works not as well with angular (without the CSFR Token), so i can not use something like flask-security. </p>
  
  <p>What is a proper way or maybe the <em>best pratice</em> for implementing User authentication with Angular und Flask? (Maybe someone knows a good example app I can learn from by example)</p>
