title: How to handle Firebase auth errors on Unity
body: <p>I created a simple password login in my Unity app following the <a href="https://firebase.google.com/docs/auth/unity/password-auth" rel="noreferrer">doc</a> and it works fine, however I would like to handle the different kind of errors and since <code>task.Exception</code> doesn't return an error code I don't know how to proceed. </p>
  
  <p>I found <a href="https://www.firebase.com/docs/web/guide/user-auth.html#section-full-error" rel="noreferrer">this</a> but it doesn't seems to be the same Firebase version since the login method is different...</p>
