I wrote a simple puppeteer code to log into websites and retrieve the amount due. I would like to build this into a website where my roommates can log in to view the breakdown of total due and have a cash app QR code embedded. I am hoping to turn this into a showcase project with responsive React and Firebase Auth.

This code file currently has login id and password written in and for obvious reasons I did not upload this to github. From what I read even private github repositories are not truly private?

How do I go about deploying this project while keeping the login info secure? I've been using cloudflare pages and it looks like only option for deployment is for me to create a git repository. Thank you.
