title: Rate limit in Firebase Authentication
body: <p>I am planning to use firebase authentication in my project. I am unable to find below in any documentation, Can someone help here?</p>
  <ol>
  <li>Any way to rate limit per user
  Ex: only 10 forget password per day will be allowed. Or in case of password mismatch, only 10 attempt will be provided.</li>
  <li>In case we have to migrate data from firebase to our own authentication system, what are the challenges?
  Thanks for help.</li>
