I wanted an alternate second factor authentication (2FA) phone number on a Raspberry Pi. So I built it for myself. I've been using it for several years. And I want to know if other folks would like to use it.<p>The software is out on [github](https://github.com/another2020githubuser/pi2fa-mvp). It is Python3 and Gtk. It uses Twilio as the back end.<p>Please take a look. And please take 5 seconds and take the [Poll](https://github.com/another2020githubuser/pi2fa-mvp/discussions/2).<p>Ask questions here, or use github discussions.<p>Thanks.
