title: Firebase authentication vs AWS Cognito
body: <p>We are building a mobile and web app on AWS using API Gateway and Lambda and are currently evaluating if we should use <strong>AWS Cognito</strong> or <strong>Firebase Auth</strong>.</p>
  <p>AWS Cognito integrates nicely into API Gateway and Lamdba e.g. only authenticated users can execute certain API calls. Can the same behaviour be reached if we use Firebase Authentication instead?
  Any good or bad experience with this?</p>
