I’ll introduce how to set up Basic Authentication with Firebase Hosting.
Background: Want to Set Up Basic Authentication with Firebase Hosting
Why Use Firebase Hosting?
The only reason for using Firebase Hosting is “because you can start using it for free.”
While Netlify also allows Basic Authentication setup, it’s not available on the free plan, so I passed on that option.
Services Used: Firebase Hosting + Cloud Functions
The services used in this article are Firebase Hosting and Cloud Functions.
