Before getting started

You can check the code, this tool never sends anything to any backend aside from google. It saves some inputs to make it easier to use in local storage but it's not doing anything with these. But always use extreme caution, download, check the code and run locally if you're unsure!

Setup project

You'll find these settings by opening http://console.firebase.google.com/ and navigating to Project overview / Project settings.

Google login

As you expect, just that one button.

Email login

Password

Phone number login

This one is a bit tricky, first you need to enter your phone number, then a captcha and then you'll get a code sent to your phone to validate with.

The user's phone number in E.164 format (e.g. +16505550101).

Current login

Change project

Pressing this will clear your local session and refresh the page allowing you to select a different project.
