title: What is the authentication period for Firebase Authentication?
body: <p>I would like to know what the default authentication period for users to be logged into Firebase is. I have an Android app where users are logging in via email/password and I want to know how long <code>FirebaseAuth.getInstance().getCurrentUser()</code> will remain not null.</p>
  
  <p>In the previous version of Firebase, the default length of time was 24 hours and could be modified via the firebase console.  Is the default amount of time still 24 hours?  Can this be modified via the console?  (I cannot seem to find anything regarding this in the latest version of Firebase)</p>
