title: Android :: How to automatically re-authenticate the User when the token expires (Email + Password authentication)
body: <p>I am using Firebase in my Android notepad app. I enabled Disk persistence and I am using Email + Password to authenticate users. Everything seems to work fine but I noticed that when the app is offline for a certain amount of time, users have to re-authenticate. Is there a way to automatically re-authenticate users when the auth token expires ?</p>
