<p>
In order to generate a token you'll need to use a service account JSON file provided by the
<a href="https://console.developers.google.com/apis/credentials/serviceaccountkey?project=_">Google Developers Console</a>
view of your Firebase project. We recommend that once you're done testing with this tool you
delete the service account you made, and create a fresh one for the integration with your
actual authentication system.
</p>
<p>To get started, select your JSON file below.</p>
