title: Firebase authentication persistence across two web apps
body: <p>I am building a platform which consists of a public facing 'website' and a PWA which will be on a subdomain on the same server.</p>
  
  <p>Both web apps use the same firebase project and I was wondering if it is possible to share authentication status between the two. i.e. can I redirect a user to the PWA side without them having to login again?</p>
  
  <p>Both apps are written with React, Redux and Node</p>
