I built a Beeper password reset tool for 'login with email/code' users

With this, you can reset your Beeper password (or set one if you never had one) by using Beeper's new 'login by email/code' method (you don't need to have your old password set/know what it is to use this)
You can find the code and other notes over on GitHub:
